By using modified\r\nHashish erosion model, the volume of material removed by impacting\r\nof abrasive particles to surface of the rotating cylindrical specimen is\r\nestimated and radius reduction at each rotation is calculated.\r\nDifferent to previous works, the proposed model considers the\r\ncontinuous change in local impact angle due to change in workpiece\r\ndiameter, axial traverse rate of the jet, the abrasive particle roundness\r\nand density. The accuracy of the proposed model is examined by\r\nexperimental tests under various traverse rates. The final diameters\r\nestimated by the proposed model are in good accordance with\r\nexperiments.","references":"[1] J. Wang, D.M.
