</p><p>機械装置では、動きを伝える元になる側を<b>原節</b>、動きを伝えられて仕事をする側を<b>従節</b>と呼び、カムは原節にあたる。カムには直線的に往復運動するものと回転運動するものがあるが、どちらも、原節の形状と速度によって従節末端が動く時間と距離が決まる。この時の従節の動作を図形化したものを<b>カム曲線</b>と呼ぶ。カム曲線はカムプロフィール（カム自体の形状や輪郭）を示すものではない。 </p><p>回転するカムは<a href="/wiki/%E8%BB%B8" class="mw-disambig" title="軸">軸</a>に取り付けられ、軸の回転角度に対応した曲面が形成されている。一般には、卵形に代表される円板カムと呼ばれる、中心から円周までの距離が一定でない板を回転する軸に取り付け、この板に接する物（板や棒）に周期的な運動を与える。
