The present research work aims to develop a mechanistic cutting force model and to study the mechanistic constants used in the force model in case of turning operation. The proposed model can be used for the reliable and accurate estimation of the cutting forces establishing relationship of various force components (cutting force and feed force) with uncut chip thickness. The accurate estimation of cutting force is required to improve thin-walled part accuracy by controlling the tool-work piece deflection induced surface errors and tool-work piece vibration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=turning" title="turning">turning</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20forces" title=" cutting forces"> cutting forces</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20constants" title=" cutting constants"> cutting constants</a>, <a href="https://publications.waset.org/abstracts/search?q=uncut%20chip%20thickness" title=" uncut chip thickness"> uncut chip thickness</a> </p> <a href="https://publications.waset.org/abstracts/30832/a-method-to-determine-cutting-force-coefficients-in-turning-using-mechanistic-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30832.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">521</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2783</span> Method and Experiment of Fabricating and Cutting the Burr for Y Shape Nanochannel </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zone-Ching%20Lin">Zone-Ching Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Hao-Yuan%20Jheng"> Hao-Yuan Jheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Shih-Hung%20Ma"> Shih-Hung Ma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper proposes using atomic force microscopy (AFM) and the concept of specific down force energy (SDFE) to establish a method for fabricating and cutting the burr for Y shape nanochannel on silicon (Si) substrate. For fabricating Y shape nanochannel, it first makes the experimental cutting path planning for fabricating Y shape nanochannel until the fifth cutting layer. Using the constant down force by AFM and SDFE theory and following the experimental cutting path planning, the cutting depth and width of each pass of Y shape nanochannel can be predicted by simulation. The paper plans the path for cutting the burr at the edge of Y shape nanochannel. Then, it carries out cutting the burr along the Y nanochannel edge by using a smaller down force. The height of standing burr at the edge is required to be below the set value of 0.54 nm. The results of simulation and experiment of fabricating and cutting the burr for Y shape nanochannel is further compared. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atomic%20force%20microscopy%20%28AFM%29" title="atomic force microscopy (AFM)">atomic force microscopy (AFM)</a>, <a href="https://publications.waset.org/abstracts/search?q=nanochannel" title=" nanochannel"> nanochannel</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20down%20force%20energy%20%28SDFE%29" title=" specific down force energy (SDFE)"> specific down force energy (SDFE)</a>, <a href="https://publications.waset.org/abstracts/search?q=Y%20shape" title=" Y shape"> Y shape</a>, <a href="https://publications.waset.org/abstracts/search?q=burr" title=" burr"> burr</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon" title=" silicon"> silicon</a> </p> <a href="https://publications.waset.org/abstracts/50887/method-and-experiment-of-fabricating-and-cutting-the-burr-for-y-shape-nanochannel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50887.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">407</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2782</span> Application of Taguchi Techniques on Machining of A356/Al2O3 Metal Matrix Nano-Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdallah%20M.%20Abdelkawy">Abdallah M.

They gain their importance due to their high strength to weight ratio. The machining problems of these new materials are less widely investigated, thus this work focuses on machining of them. Aluminum-Silicon (A356)/ MMNC dispersed with alumina (Al2O3) is important in many applications include engine blocks. The final finish process of this application depends heavily on machining. The most important machining parameter studied includes: cutting force and surface roughness. Experimental trails are performed on the number of special samples of MMNC (with different Al2O3%) where the relation between Al2O3% and cutting speed, feed rate and cutting depth with cutting force and surface roughness were studied. The data obtained were statistically analyzed using Analysis of variance (ANOVA) to define the significant factors on both cutting force and surface roughness and their level of confident. Response Surface Methodology (RSM) is used to build a model relating cutting conditions and Al2O3% to the cutting force and surface roughness. The results have shown that feed and depth of cut have the major contribution on the cutting force and the surface roughness followed by cutting speed and nano-percent in MMNCs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machinability" title="machinability">machinability</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20force" title=" cutting force"> cutting force</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a>, <a href="https://publications.waset.org/abstracts/search?q=Ra" title=" Ra"> Ra</a>, <a href="https://publications.waset.org/abstracts/search?q=RSM" title=" RSM"> RSM</a>, <a href="https://publications.waset.org/abstracts/search?q=ANOVA" title=" ANOVA"> ANOVA</a>, <a href="https://publications.waset.org/abstracts/search?q=MMNCs" title=" MMNCs"> MMNCs</a> </p> <a href="https://publications.waset.org/abstracts/20821/application-of-taguchi-techniques-on-machining-of-a356al2o3-metal-matrix-nano-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20821.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2781</span> Neural Network Monitoring Strategy of Cutting Tool Wear of Horizontal High Speed Milling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kious%20Mecheri">Kious Mecheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadjadj%20Abdechafik"> Hadjadj Abdechafik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ameur%20Aissa"> Ameur Aissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The wear of cutting tool degrades the quality of the product in the manufacturing processes. The online monitoring of the cutting tool wear level is very necessary to prevent the deterioration of the quality of machining. Unfortunately there is not a direct manner to measure the cutting tool wear online. Consequently we must adopt an indirect method where wear will be estimated from the measurement of one or more physical parameters appearing during the machining process such as the cutting force, the vibrations, or the acoustic emission etc. In this work, a neural network system is elaborated in order to estimate the flank wear from the cutting force measurement and the cutting conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flank%20wear" title="flank wear">flank wear</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20forces" title=" cutting forces"> cutting forces</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20speed%20milling" title=" high speed milling"> high speed milling</a>, <a href="https://publications.waset.org/abstracts/search?q=signal%20processing" title=" signal processing"> signal processing</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a> </p> <a href="https://publications.waset.org/abstracts/6906/neural-network-monitoring-strategy-of-cutting-tool-wear-of-horizontal-high-speed-milling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6906.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">393</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2780</span> A Prediction of Cutting Forces Using Extended Kienzle Force Model Incorporating Tool Flank Wear Progression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wu%20Peng">Wu Peng</a>, <a href="https://publications.waset.org/abstracts/search?q=Anders%20Liljerehn"> Anders Liljerehn</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Magnevall"> Martin Magnevall</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In metal cutting, tool wear gradually changes the micro geometry of the cutting edge. Today there is a significant gap in understanding the impact these geometrical changes have on the cutting forces which governs tool deflection and heat generation in the cutting zone. Accurate models and understanding of the interaction between the work piece and cutting tool leads to improved accuracy in simulation of the cutting process. These simulations are useful in several application areas, e.g., optimization of insert geometry and machine tool monitoring. This study aims to develop an extended Kienzle force model to account for the effect of rake angle variations and tool flank wear have on the cutting forces. In this paper, the starting point sets from cutting force measurements using orthogonal turning tests of pre-machined flanches with well-defined width, using triangular coated inserts to assure orthogonal condition. The cutting forces have been measured by dynamometer with a set of three different rake angles, and wear progression have been monitored during machining by an optical measuring collaborative robot. The method utilizes the measured cutting forces with the inserts flank wear progression to extend the mechanistic cutting forces model with flank wear as an input parameter. The adapted cutting forces model is validated in a turning process with commercial cutting tools. This adapted cutting forces model shows the significant capability of prediction of cutting forces accounting for tools flank wear and different-rake-angle cutting tool inserts. The result of this study suggests that the nonlinear effect of tools flank wear and interaction between the work piece and the cutting tool can be considered by the developed cutting forces model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cutting%20force" title="cutting force">cutting force</a>, <a href="https://publications.waset.org/abstracts/search?q=kienzle%20model" title=" kienzle model"> kienzle model</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20model" title=" predictive model"> predictive model</a>, <a href="https://publications.waset.org/abstracts/search?q=tool%20flank%20wear" title=" tool flank wear"> tool flank wear</a> </p> <a href="https://publications.waset.org/abstracts/152477/a-prediction-of-cutting-forces-using-extended-kienzle-force-model-incorporating-tool-flank-wear-progression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152477.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">108</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2779</span> Investigations in Machining of Hot Work Tool Steel with Mixed Ceramic Tool</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Varaprasad">B.

In the present study, the effects of cutting speed, feed rate and Depth of Cut (DOC) on cutting forces, specific cutting force, power and surface roughness in the hard turning are experimentally investigated. Experiments are carried out using mixed ceramic(Al2O3+TiC) cutting tool of corner radius 0.8mm, in turning operations on AISI H13 tool steel, heat treated to a hardness of 62 HRC. Based on Design of Experiments (DOE), a total of 20 tests are carried out. The range of each one of the three parameters is set at three different levels, viz, low, medium and high. The validity of the model is checked by Analysis of variance (ANOVA). Predicted models are derived from regression analysis. Comparison of experimental and predicted values of specific cutting force, power and surface roughness shows that good agreement has been achieved between them. Therefore, the developed model may be recommended to be used for predicting specific cutting force, power and surface roughness in hard turning of tool steel that is AISI H13 steel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hard%20turning" title="hard turning">hard turning</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20cutting%20force" title=" specific cutting force"> specific cutting force</a>, <a href="https://publications.waset.org/abstracts/search?q=power" title=" power"> power</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a>, <a href="https://publications.waset.org/abstracts/search?q=AISI%20H13" title=" AISI H13"> AISI H13</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20ceramic" title=" mixed ceramic"> mixed ceramic</a> </p> <a href="https://publications.waset.org/abstracts/19263/investigations-in-machining-of-hot-work-tool-steel-with-mixed-ceramic-tool" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19263.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">700</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2778</span> An Efficient Approach for Shear Behavior Definition of Plant Stalk </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20R.%20Kamandar">M.

Massah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The information of the impact cutting behavior of plants stalk plays an important role in the design and fabrication of plants cutting equipment. It is difficult to investigate a theoretical method for defining cutting properties of plants stalks because the cutting process is complex. Thus, it is necessary to set up an experimental approach to determine cutting parameters for a single stalk. To measure the shear force, shear energy and shear strength of plant stalk, a special impact cutting tester was fabricated. It was similar to an Izod impact cutting tester for metals but a cutting blade and data acquisition system were attached to the end of pendulum's arm. The apparatus was included four strain gages and a digital indicator to show the real-time cutting force of plant stalk. To measure the shear force and also testing the apparatus, two plants’ stalks, like buxus and privet, were selected. The samples (buxus and privet stalks) were cut under impact cutting process at four loading rates 1, 2, 3 and 4 m.s<sup>-1</sup> and three internodes fifth, tenth and fifteenth by the apparatus. At buxus cutting analysis: the minimum value of cutting energy was obtained at fifth internode and loading rate 4 m.s<sup>-1</sup> and the maximum value of shear energy was obtained at fifteenth internode and loading rate 1 m.s<sup>-1</sup>. At privet cutting analysis: the minimum value of shear consumption energy was obtained at fifth internode and loading rate: 4 m.s<sup>-1</sup> and the maximum value of shear energy was obtained at fifteenth internode and loading rate: 1 m.s<sup>-1</sup>. The statistical analysis at both plants showed that the increase of impact cutting speed would decrease the shear consumption energy and shear strength. In two scenarios, the results showed that with increase the cutting speed, shear force would decrease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Buxus" title="Buxus">Buxus</a>, <a href="https://publications.waset.org/abstracts/search?q=Privet" title=" Privet"> Privet</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20cutting" title=" impact cutting"> impact cutting</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20energy" title=" shear energy"> shear energy</a> </p> <a href="https://publications.waset.org/abstracts/109634/an-efficient-approach-for-shear-behavior-definition-of-plant-stalk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109634.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">125</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2777</span> Experimental Studies on the Effect of Rake Angle on Turning Ti-6Al-4V with TiAlN Coated Carbides</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Satyanarayana%20Kosaraju">Satyanarayana Kosaraju</a>, <a href="https://publications.waset.org/abstracts/search?q=Venu%20Gopal%20Anne"> Venu Gopal Anne</a>, <a href="https://publications.waset.org/abstracts/search?q=Sateesh%20Nagari"> Sateesh Nagari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the effect of cutting speed, feedrate and rake angle in tool geometry on cutting forces and temperature generated on the tool tip in turning were investigated.

The main cutting force was observed to have a decreasing trend and temperature found to be increasing trend as the rake angle increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cutting%20force" title="cutting force">cutting force</a>, <a href="https://publications.waset.org/abstracts/search?q=tool%20tip%20temperature" title=" tool tip temperature"> tool tip temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=rake%20angle" title=" rake angle"> rake angle</a>, <a href="https://publications.waset.org/abstracts/search?q=machining" title=" machining"> machining</a> </p> <a href="https://publications.waset.org/abstracts/37425/experimental-studies-on-the-effect-of-rake-angle-on-turning-ti-6al-4v-with-tialn-coated-carbides" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37425.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">506</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2776</span> Machining Responce of Austempered Ductile Iron with Varying Cutting Speed and Depth of Cut</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prashant%20Parhad">Prashant Parhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinayak%20Dakre"> Vinayak Dakre</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajay%20Likhite"> Ajay Likhite</a>, <a href="https://publications.waset.org/abstracts/search?q=Jatin%20Bhatt"> Jatin Bhatt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work mainly focuses on machinability studies of Austempered Ductile Iron (ADI). The Ductile Iron (DI) was austempered at 250 oC for different durations and the process window for austempering was established by studying the microstructure. The microstructural characterization of the material was done using optical microscopy, SEM and XRD. The samples austempered as per the process window were then subjected to turning using a TiAlN-coated tungsten carbide insert to study the effect of cutting parameters, namely the cutting speed and the depth of cut. The effect was investigated in terms of cutting forces required as well as the surface roughness obtained. The turning was conducted on a CNC turning machine and primary (Fx), radial (Fy) and feed (Fz) cutting forces were quantified with a three-component dynamometer. It was observed that the magnitude of radial force was more than that of primary cutting force for all cutting speed and for various depths of cut studied. It has also been seen that increasing the cutting speed improves the surface quality. The observed machinability behaviour was investigated in light of the microstructure of the material obtained under the given austempering conditions and a structure-property- co-relation was established between the two. For all cutting speed and depth of cut, the best machining response in terms of cutting forces and surface quality was obtained towards the centre of process window. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=process%20window" title="process window">process window</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20speed" title=" cutting speed"> cutting speed</a>, <a href="https://publications.waset.org/abstracts/search?q=depth%20of%20cut" title=" depth of cut"> depth of cut</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a> </p> <a href="https://publications.waset.org/abstracts/31800/machining-responce-of-austempered-ductile-iron-with-varying-cutting-speed-and-depth-of-cut" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31800.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">368</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2775</span> Parametric Study and Modelling of Orthogonal Cutting Process for AISI 4340 and Ti-6Al-4V Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Purnank%20Bhatt">Purnank Bhatt</a>, <a href="https://publications.waset.org/abstracts/search?q=Mit%20Shah"> Mit Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Pawan%20Nagda"> Pawan Nagda</a>, <a href="https://publications.waset.org/abstracts/search?q=Vimal%20Jasoliya"> Vimal Jasoliya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The influence of parameters like velocity and depth of cut on cutting forces is investigated for the empirical relation of the coefficient of friction derived for CRS 1018 for different materials like AISI 4340 and Ti6Al4V.

Therefore, this study proposes an accurate ball end milling process modeling which includes also the influence of tool workpiece inclination. In addition, a characterization of residual stresses resulting of thermo mechanical loading in the workpiece was also presented. Moreover, the study of the influence of tool workpiece inclination and cutting parameters was made on residual stresses distribution. In order to achieve the predetermination of cutting forces and residual stresses during a milling operation, a thermo mechanical three-dimensional numerical model of ball end milling was developed. Furthermore, an experimental companion of ball end milling tests was realized on a 5-axis machining center to determine the cutting forces and characterize the residual stresses. The simulation results are compared with the experiment to validate the Finite Element Model and subsequently identify the optimum inclination angle and cutting parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ball%20end%20milling" title="ball end milling">ball end milling</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20forces" title=" cutting forces"> cutting forces</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20parameters" title=" cutting parameters"> cutting parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20stress" title=" residual stress"> residual stress</a>, <a href="https://publications.waset.org/abstracts/search?q=tool-workpiece%20inclination" title=" tool-workpiece inclination"> tool-workpiece inclination</a> </p> <a href="https://publications.waset.org/abstracts/46279/experimental-and-numerical-analysis-of-the-effects-of-ball-end-milling-process-upon-residual-stresses-and-cutting-forces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46279.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">308</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2772</span> Analysis of Rock Cutting Progress with a New Axe-Shaped PDC Cutter to Improve PDC Bit Performance in Elastoplastic Formation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fangyuan%20Shao">Fangyuan Shao</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Liu"> Wei Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Deli%20Gao"> Deli Gao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polycrystalline diamond compact (PDC) bits have occupied a large market of unconventional oil and gas drilling. The application of PDC bits benefits from the efficient rock breaking of PDC cutters. In response to increasingly complex formations, many shaped cutters have been invited, but many of them have not been solved by the mechanism of rock breaking. In this paper, two kinds of PDC cutters: a new axe-shaped (NAS) cutter and cylindrical cutter (benchmark) were studied by laboratory experiments. NAS cutter is obtained by optimizing two sides of axe-shaped cutter with curved surfaces. All the cutters were put on a vertical turret lathe (VTL) in the laboratory for cutting tests. According to the cutting distance, the VTL tests can be divided into two modes: single-turn rotary cutting and continuous cutting. The cutting depth of cutting (DOC) was set at 1.0 mm and 2.0 mm in the former mode. The later mode includes a dry VTL test for thermal stability and a wet VTL test for wear resistance. Load cell and 3D optical profiler were used to obtain the value of cutting forces and wear area, respectively. Based on the findings of the single-turn rotary cutting VTL tests, the performance of A NAS cutter was better than the benchmark cutter on elastoplastic material cutting. The cutting forces (normal forces, tangential force, and radial force) and special mechanical energy (MSE) of a NAS cutter were lower than that of the benchmark cutter under the same condition. It meant that a NAS cutter was more efficient on elastoplastic material breaking. However, the wear resistance of a new axe-shaped cutter was higher than that of a benchmark cutter. The results of the dry VTL test showed that the thermal stability of a NAS cutter was higher than that of a benchmark cutter. The cutting efficiency can be improved by optimizing the geometric structure of the PDC cutter. The change of thermal stability may be caused by the decrease of the contact area between cutter and rock at given DOC. The conclusions of this paper can be used as an important reference for PDC cutters designers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axe-shaped%20cutter" title="axe-shaped cutter">axe-shaped cutter</a>, <a href="https://publications.waset.org/abstracts/search?q=PDC%20cutter" title=" PDC cutter"> PDC cutter</a>, <a href="https://publications.waset.org/abstracts/search?q=rotary%20cutting%20test" title=" rotary cutting test"> rotary cutting test</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20turret%20lathe" title=" vertical turret lathe"> vertical turret lathe</a> </p> <a href="https://publications.waset.org/abstracts/139822/analysis-of-rock-cutting-progress-with-a-new-axe-shaped-pdc-cutter-to-improve-pdc-bit-performance-in-elastoplastic-formation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139822.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">203</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2771</span> Simulating Drilling Using a CAD System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Panagiotis%20Kyratsis">Panagiotis Kyratsis</a>, <a href="https://publications.waset.org/abstracts/search?q=Konstantinos%20Kakoulis"> Konstantinos Kakoulis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the rapid development of CAD systems’ programming environments results in the creation of multiple downstream applications, which are developed and becoming increasingly available.

In order to assess the quality of nano cutting fluids used during machining, cutting temperatures, cutting forces and surface roughness under constant cutting conditions are measured. The influence of two types of nanofluids prepared from nano boric acid and CNT particles mixed separately with coconut oil, on machining performance during turning operation is examined. Comparative analysis of the results obtained is done under dry and lubricant environments. Results obtained using cutting fluids prepared from vegetable oil based nanofluids are encouraging and more pronouncing by the application of CCCNT at machining zone. The extent of improvement in reduction of cutting temperatures, main cutting force, tool wear and surface roughness is tracked to be 13%, 37.5%, 44% and 40% respectively by the application of CCCNT compared to dry machining. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title="nanoparticles">nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetable%20oil" title=" vegetable oil"> vegetable oil</a>, <a href="https://publications.waset.org/abstracts/search?q=machining" title=" machining"> machining</a>, <a href="https://publications.waset.org/abstracts/search?q=MQL" title=" MQL"> MQL</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a> </p> <a href="https://publications.waset.org/abstracts/40471/effect-of-vegetable-oil-based-nanofluids-on-machining-performance-an-experimental-investigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40471.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">359</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2769</span> Machinability Analysis in Drilling Flax Fiber-Reinforced Polylactic Acid Bio-Composite Laminates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amirhossein%20Lotfi">Amirhossein Lotfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Huaizhong%20Li"> Huaizhong Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Dzung%20Viet%20Dao"> Dzung Viet Dao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Interest in natural fiber-reinforced composites (NFRC) is progressively growing both in terms of academia research and industrial applications thanks to their abundant advantages such as low cost, biodegradability, eco-friendly nature and relatively good mechanical properties. However, their widespread use is still presumed as challenging because of the specificity of their non-homogeneous structure, limited knowledge on their machinability characteristics and parameter settings, to avoid defects associated with the machining process. The present work is aimed to investigate the effect of the cutting tool geometry and material on the drilling-induced delamination, thrust force and hole quality produced when drilling a fully biodegradable flax/poly (lactic acid) composite laminate. Three drills with different geometries and material were used at different drilling conditions to evaluate the machinability of the fabricated composites. The experimental results indicated that the choice of cutting tool, in terms of material and geometry, has a noticeable influence on the cutting thrust force and subsequently drilling-induced damages. The lower value of thrust force and better hole quality was observed using high-speed steel (HSS) drill, whereas Carbide drill (with point angle of 130<sup>o</sup>) resulted in the highest value of thrust force. Carbide drill presented higher wear resistance and stability in variation of thrust force with a number of holes drilled, while HSS drill showed the lower value of thrust force during the drilling process. Finally, within the selected cutting range, the delamination damage increased noticeably with feed rate and moderately with spindle speed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20fiber%20reinforced%20composites" title="natural fiber reinforced composites">natural fiber reinforced composites</a>, <a href="https://publications.waset.org/abstracts/search?q=delamination" title=" delamination"> delamination</a>, <a href="https://publications.waset.org/abstracts/search?q=thrust%20force" title=" thrust force"> thrust force</a>, <a href="https://publications.waset.org/abstracts/search?q=machinability" title=" machinability"> machinability</a> </p> <a href="https://publications.waset.org/abstracts/111475/machinability-analysis-in-drilling-flax-fiber-reinforced-polylactic-acid-bio-composite-laminates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111475.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2768</span> Optimization of Cutting Forces in Drilling of Polimer Composites via Taguchi Methodology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eser%20Yarar">Eser Yarar</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahri%20Vatansever"> Fahri Vatansever</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Tamer%20Erturk"> A.

The drilling capability of the synthetic polymer composite material was investigated by measuring the cutting forces using different tool diameters, feed rate and high cutting speed parameters. Cutting forces were measured using a dynamometer in the experiments. In order to evaluate the results of the experiment, the Taguchi experimental design method was used. According to the results, the optimum cutting parameters were obtained for 0.1 mm/rev, 1070 rpm and 2 mm diameter drill bit. Verification tests were performed for the optimum cutting parameters obtained according to the model.

It gives the ability to produce any complex parts directly from a computer-aided design (CAD) model without tools and dies, and with a variety of materials. However, the quality of the surface finish in EBM process has limitations to meeting the performance requirements of additively manufactured components. The aim of this study is to investigate the cutting forces induced during milling Ti6Al4V produced by EBM as well as the surface quality of the milled surfaces. The effects of cutting speed and radial depth of cut on the cutting forces, surface roughness, and surface morphology were investigated. The results indicated that the cutting speed was found to be proportional to the resultant cutting force at any cutting conditions while the surface roughness improved significantly with the increase in cutting speed and radial depth of cut. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electron%20beam%20melting" title="electron beam melting">electron beam melting</a>, <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title=" additive manufacturing"> additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=Ti6Al4V" title=" Ti6Al4V"> Ti6Al4V</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20morphology" title=" surface morphology"> surface morphology</a> </p> <a href="https://publications.waset.org/abstracts/122114/effects-of-milling-process-parameters-on-cutting-forces-and-surface-roughness-when-finishing-ti6al4v-produced-by-electron-beam-melting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122114.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2766</span> Analysis of the Cutting Force with Ultrasonic Assisted Manufacturing of Steel (S235JR)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Zopf">Philipp Zopf</a>, <a href="https://publications.waset.org/abstracts/search?q=Franz%20Haas"> Franz Haas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Manufacturing of very hard and refractory materials like ceramics, glass or carbide poses particular challenges on tools and machines. The company Sauer GmbH developed especially for this application area ultrasonic tool holders working in a frequency range from 15 to 60 kHz and superimpose the common tool movement in the vertical axis. This technique causes a structural weakening in the contact area and facilitates the machining. The possibility of the force reduction for these special materials especially in drilling of carbide with diamond tools up to 30 percent made the authors try to expand the application range of this method. To make the results evaluable, the authors decide to start with existing processes in which the positive influence of the ultrasonic assistance is proven to understand the mechanism. The comparison of a grinding process the Institute use to machine materials mentioned in the beginning and steel could not be more different. In the first case, the authors use tools with geometrically undefined edges. In the second case, the edges are geometrically defined. To get valid results of the tests, the authors decide to investigate two manufacturing methods, drilling and milling. The main target of the investigation is to reduce the cutting force measured with a force measurement platform underneath the workpiece. Concerning to the direction of the ultrasonic assistance, the authors expect lower cutting forces and longer endurance of the tool in the drilling process. To verify the frequencies and the amplitudes an FFT-analysis is performed. It shows the increasing damping depending on the infeed rate of the tool. The reducing of amplitude of the cutting force comes along. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drilling" title="drilling">drilling</a>, <a href="https://publications.waset.org/abstracts/search?q=machining" title=" machining"> machining</a>, <a href="https://publications.waset.org/abstracts/search?q=milling" title=" milling"> milling</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic" title=" ultrasonic"> ultrasonic</a> </p> <a href="https://publications.waset.org/abstracts/69538/analysis-of-the-cutting-force-with-ultrasonic-assisted-manufacturing-of-steel-s235jr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69538.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">274</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2765</span> Orthogonal Metal Cutting Simulation of Steel AISI 1045 via Smoothed Particle Hydrodynamic Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Hamed%20Hashemi%20Sohi">Seyed Hamed Hashemi Sohi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Jo%20Denoga"> Gerald Jo Denoga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Machining or metal cutting is one of the most widely used production processes in industry. The quality of the process and the resulting machined product depends on parameters like tool geometry, material, and cutting conditions. However, the relationships of these parameters to the cutting process are often based mostly on empirical knowledge. In this study, computer modeling and simulation using LS-DYNA software and a Smoothed Particle Hydrodynamic (SPH) methodology, was performed on the orthogonal metal cutting process to analyze three-dimensional deformation of AISI 1045 medium carbon steel during machining. The simulation was performed using the following constitutive models: the Power Law model, the Johnson-Cook model, and the Zerilli-Armstrong models (Z-A). The outcomes were compared against the simulated results obtained by Cenk Kiliçaslan using the Finite Element Method (FEM) and the empirical results of Jaspers and Filice. The analysis shows that the SPH method combined with the Zerilli-Armstrong constitutive model is a viable alternative to simulating the metal cutting process. The tangential force was overestimated by 7%, and the normal force was underestimated by 16% when compared with empirical values. The simulation values for flow stress versus strain at various temperatures were also validated against empirical values. The SPH method using the Z-A model has also proven to be robust against issues of time-scaling. Experimental work was also done to investigate the effects of friction, rake angle and tool tip radius on the simulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metal%20cutting" title="metal cutting">metal cutting</a>, <a href="https://publications.waset.org/abstracts/search?q=smoothed%20particle%20hydrodynamics" title=" smoothed particle hydrodynamics"> smoothed particle hydrodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=constitutive%20models" title=" constitutive models"> constitutive models</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental" title=" experimental"> experimental</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20forces%20analyses" title=" cutting forces analyses"> cutting forces analyses</a> </p> <a href="https://publications.waset.org/abstracts/70310/orthogonal-metal-cutting-simulation-of-steel-aisi-1045-via-smoothed-particle-hydrodynamic-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70310.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">261</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2764</span> Numerical Simulation of Transient 3D Temperature and Kerf Formation in Laser Fusion Cutting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Kheloufi">Karim Kheloufi</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Hachemi%20Amara"> El Hachemi Amara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, a three-dimensional transient numerical model was developed to study the temperature field and cutting kerf shape during laser fusion cutting. The finite volume model has been constructed, based on the Navier–Stokes equations and energy conservation equation for the description of momentum and heat transport phenomena, and the Volume of Fluid (VOF) method for free surface tracking. The Fresnel absorption model is used to handle the absorption of the incident wave by the surface of the liquid metal and the enthalpy-porosity technique is employed to account for the latent heat during melting and solidification of the material. To model the physical phenomena occurring at the liquid film/gas interface, including momentum/heat transfer, a new approach is proposed which consists of treating friction force, pressure force applied by the gas jet and the heat absorbed by the cutting front surface as source terms incorporated into the governing equations. All these physics are coupled and solved simultaneously in Fluent CFD®. The main objective of using a transient phase change model in the current case is to simulate the dynamics and geometry of a growing laser-cutting generated kerf until it becomes fully developed. The model is used to investigate the effect of some process parameters on temperature fields and the formed kerf geometry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laser%20cutting" title="laser cutting">laser cutting</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20flow" title=" fluid flow"> fluid flow</a> </p> <a href="https://publications.waset.org/abstracts/14414/numerical-simulation-of-transient-3d-temperature-and-kerf-formation-in-laser-fusion-cutting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14414.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">339</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2763</span> Effects of Tool State on the Output Parameters of Front Milling Using Discrete Wavelet Transform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bruno%20S.%20Soria">Bruno S.

The vibration generated during material cutting can also directly affect the surface quality and life of the cutting tool. In this work, the effect of mechanical broken failure (MBF) on carbide insert tools during face milling of AISI 304 stainless steel was evaluated using three levels of feed rate and two spindle speeds for each tool condition: three carbide inserts have perfect geometry, and three other carbide inserts have MBF. The axial and radial depths remained constant. The cutting forces were determined through a sensory system that consists of a piezoelectric dynamometer and data acquisition system. Discrete Wavelet Transform was used to separate the static part of the signals of force and vibration. The roughness of the machined surface was analyzed for each machining condition. The MBF of the tool increased the intensity and force of vibration and worsened the roughness factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=face%20milling" title="face milling">face milling</a>, <a href="https://publications.waset.org/abstracts/search?q=stainless%20steel" title=" stainless steel"> stainless steel</a>, <a href="https://publications.waset.org/abstracts/search?q=tool%20condition%20monitoring" title=" tool condition monitoring"> tool condition monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=wavelet%20discrete%20transform" title=" wavelet discrete transform"> wavelet discrete transform</a> </p> <a href="https://publications.waset.org/abstracts/109363/effects-of-tool-state-on-the-output-parameters-of-front-milling-using-discrete-wavelet-transform" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109363.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2762</span> Fracture Control of the Soda-Lime Glass in Laser Thermal Cleavage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jehnming%20Lin">Jehnming Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effects of the contact ball-lens on the soda lime glass in laser thermal cleavage with a cw Nd-YAG laser were investigated in this study. A contact ball-lens was adopted to generate a bending force on the crack formation of the soda-lime glass in the laser cutting process. The Nd-YAG laser beam (wavelength of 1064 nm) was focused through the ball-lens and transmitted to the soda-lime glass, which was coated with a carbon film on the surface with a bending force from a ball-lens to generate a tensile stress state on the surface cracking. The fracture was controlled by the contact ball-lens and a straight cutting was tested to demonstrate the feasibility. Experimental observations on the crack propagation from the leading edge, main section and trailing edge of the glass sheet were compared with various mechanical and thermal loadings. Further analyses on the stress under various laser powers and contact ball loadings were made to characterize the innovative technology. The results show that the distributions of the side crack at the leading and trailing edges are mainly dependent on the boundary condition, contact force, cutting speed and laser power. With the increase of the mechanical and thermal loadings, the region of the side cracks might be dramatically reduced with proper selection of the geometrical constraints. Therefore, the application of the contact ball-lens is a possible way to control the fracture in laser cleavage with improved cutting qualities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laser%20cleavage" title="laser cleavage">laser cleavage</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20analysis" title=" stress analysis"> stress analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=crack%20visualization" title=" crack visualization"> crack visualization</a>, <a href="https://publications.waset.org/abstracts/search?q=laser" title=" laser"> laser</a> </p> <a href="https://publications.waset.org/abstracts/31854/fracture-control-of-the-soda-lime-glass-in-laser-thermal-cleavage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31854.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">436</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2761</span> A Machining Method of Cross-Shape Nano Channel and Experiments for Silicon Substrate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zone-Ching%20Lin">Zone-Ching Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Hao-Yuan%20Jheng"> Hao-Yuan Jheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Zih-Wun%20Jhang"> Zih-Wun Jhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper innovatively proposes using the concept of specific down force energy (SDFE) and AFM machine to establish a machining method of cross-shape nanochannel on single-crystal silicon substrate. As for machining a cross-shape nanochannel by AFM machine, the paper develop a method of machining cross-shape nanochannel groove at a fixed down force by using SDFE theory and combining the planned cutting path of cross-shape nanochannel up to 5th machining layer it finally achieves a cross-shape nanochannel at a cutting depth of around 20nm. Since there may be standing burr at the machined cross-shape nanochannel edge, the paper uses a smaller down force to cut the edge of the cross-shape nanochannel in order to lower the height of standing burr and converge the height of standing burr at the edge to below 0.54nm as set by the paper. Finally, the paper conducts experiments of machining cross-shape nanochannel groove on single-crystal silicon by AFM probe, and compares the simulation and experimental results. It is proved that this proposed machining method of cross-shape nanochannel is feasible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atomic%20force%20microscopy%20%28AFM%29" title="atomic force microscopy (AFM)">atomic force microscopy (AFM)</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-shape%20nanochannel" title=" cross-shape nanochannel"> cross-shape nanochannel</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon%20substrate" title=" silicon substrate"> silicon substrate</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20down%20force%20energy%20%28SDFE%29" title=" specific down force energy (SDFE)"> specific down force energy (SDFE)</a> </p> <a href="https://publications.waset.org/abstracts/26057/a-machining-method-of-cross-shape-nano-channel-and-experiments-for-silicon-substrate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26057.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2760</span> Analysis of Drilling Parameters for Al-Mg2-Si Metal Matrix Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Jahangir">S.

The performance of different drill bits of different morphology and material was studied and analysed using experimental data. For theoretical calculations of axial thrust force and required power calculation, material factor “K” was obtained from different data charts and at the same time cutting forces (drilling forces) were practically obtained using a Peizo electric force dynamometer. These results show the role of reinforcement particles on the machinability of MMCs and provide a useful guide for a better control and optimized drilling parameters for the drilling process.

Instead of required parameters need to be measured such as temperature, vibration, and tool wear that emerged during cutting process; detailed analysis of the sound emerged during cutting process will provide detection of various data that included in the cutting process by the much more easy and economic way.

The premature removal of the cutting tool results in high cost of machining since the parcel relating to the cost of the cutting tool increases. On the other hand, the late exchange of cutting tool also increases the cost of production because getting parts out of the preset tolerances may require rework for its use when it does not cause bigger problems such as breaking of cutting tools or the loss of the part. Therefore, the right time to exchange the tool should be well defined when wanted to minimize production costs. When the flank wear is the limiting tool life, the time predetermination that a cutting tool must be used for the machining occurs within the limits of tolerance can be done without difficulty. This paper aims to show how the life of the cutting tool can be calculated taking into account the cutting parameters (cutting speed, feed and depth of cut), workpiece material, power of the machine, the dimensional tolerance of the part, the finishing surface, the geometry of the cutting tool and operating conditions of the machine tool, once known the parameters of Taylor algebraic structure. These parameters were raised for the ABNT 1038 steel machined with cutting tools of hard metal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machining" title="machining">machining</a>, <a href="https://publications.waset.org/abstracts/search?q=productions" title=" productions"> productions</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20condition" title=" cutting condition"> cutting condition</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing" title=" manufacturing"> manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement" title=" measurement"> measurement</a> </p> <a href="https://publications.waset.org/abstracts/9191/life-prediction-of-cutting-tool-by-the-workpiece-cutting-condition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9191.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">634</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2757</span> Investigation of the Possibility of Using Carbon Onion Nanolubrication with DLC Cutting Tool to Reduce the Machining Power Consumption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20A.%20D.%20Sarhan">Ahmed A.

In the CNC machining field, the key solution for this issue is by increasing the effectiveness of the existing lubrication systems as it could reduce the power required to overcome the friction component in machining process. For more improvement, introducing the nanolubrication could produce much less power consumption as the rolling action of billions units of nanoparticle in the tool chip interface could reduce the cutting forces significantly. In this research, the possibility of using carbon onion nanolubrication with DLC cutting tool is investigated to reduce the machining power consumption. Carbon onion nanolubrication has been successfully developed with high tribology performance and mixed with ordinary mineral oil. The proper sonification method is used to provide a way to mix and suspend the particles thoroughly and efficiently. Furthermore, Diamond-Like Carbon (DLC) cutting tool is used and expected to play significant role in reducing friction and cutting forces and increasing abrasion resistance. The results showed significant reduction of the cutting force and the working power compared with the other conditions of using carbon black and normal lubrication systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20onion" title="carbon onion">carbon onion</a>, <a href="https://publications.waset.org/abstracts/search?q=nanolubrication" title=" nanolubrication"> nanolubrication</a>, <a href="https://publications.waset.org/abstracts/search?q=machining%20power%20consumption" title=" machining power consumption"> machining power consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=DLC%20cutting%20tool" title=" DLC cutting tool"> DLC cutting tool</a> </p> <a href="https://publications.waset.org/abstracts/3304/investigation-of-the-possibility-of-using-carbon-onion-nanolubrication-with-dlc-cutting-tool-to-reduce-the-machining-power-consumption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3304.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">432</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2756</span> Prediction of Cutting Tool Life in Drilling of Reinforced Aluminum Alloy Composite Using a Fuzzy Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20T.%20Hayajneh">Mohammed T. Hayajneh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Machining of Metal Matrix Composites (MMCs) is very significant process and has been a main problem that draws many researchers to investigate the characteristics of MMCs during different machining process. The poor machining properties of hard particles reinforced MMCs make drilling process a rather interesting task. Unlike drilling of conventional materials, many problems can be seriously encountered during drilling of MMCs, such as tool wear and cutting forces. Cutting tool wear is a very significant concern in industries. Cutting tool wear not only influences the quality of the drilled hole, but also affects the cutting tool life. Prediction the cutting tool life during drilling is essential for optimizing the cutting conditions. However, the relationship between tool life and cutting conditions, tool geometrical factors and workpiece material properties has not yet been established by any machining theory. In this research work, fuzzy subtractive clustering system has been used to model the cutting tool life in drilling of Al<sub>2</sub>O<sub>3</sub> particle reinforced aluminum alloy composite to investigate of the effect of cutting conditions on cutting tool life. This investigation can help in controlling and optimizing of cutting conditions when the process parameters are adjusted. The built model for prediction the tool life is identified by using drill diameter, cutting speed, and cutting feed rate as input data. The validity of the model was confirmed by the examinations under various cutting conditions. Experimental results have shown the efficiency of the model to predict cutting tool life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite" title="composite">composite</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy" title=" fuzzy"> fuzzy</a>, <a href="https://publications.waset.org/abstracts/search?q=tool%20life" title=" tool life"> tool life</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a> </p> <a href="https://publications.waset.org/abstracts/42835/prediction-of-cutting-tool-life-in-drilling-of-reinforced-aluminum-alloy-composite-using-a-fuzzy-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42835.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2755</span> Effect of Composite Material on Damping Capacity Improvement of Cutting Tool in Machining Operation Using Taguchi Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siamak%20Ghorbani">Siamak Ghorbani</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikolay%20Ivanovich%20Polushin"> Nikolay Ivanovich Polushin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chatter vibrations, occurring during cutting process, cause vibration between the cutting tool and workpiece, which deteriorates surface roughness and reduces tool life. The purpose of this study is to investigate the influence of cutting parameters and tool construction on surface roughness and vibration in turning of aluminum alloy AA2024. A new design of cutting tool is proposed, which is filled up with epoxy granite in order to improve damping capacity of the tool. Experiments were performed at the lathe using carbide cutting insert coated with TiC and two different cutting tools made of AISI 5140 steel. Taguchi L9 orthogonal array was applied to design of experiment and to optimize cutting conditions. By the help of signal-to-noise ratio and analysis of variance the optimal cutting condition and the effect of the cutting parameters on surface roughness and vibration were determined. Effectiveness of Taguchi method was verified by confirmation test. It was revealed that new cutting tool with epoxy granite has reduced vibration and surface roughness due to high damping properties of epoxy granite in toolholder. <p
