During ausform finishing process of hardened gears, there is plastic displacement of metal on the tooth surface and the distortion of tooth profile.
在齿轮热滚挤加工中，轮齿上的金属在强制挤压力的作用下沿齿面产生塑性流动，使齿形发生变化。

The method of gear dynamic mutual abrasion is a method in which the dynamic force on tooth surface was used to do the precision finishing.
齿轮动力互研法是利用齿面动态力达到齿轮精加工目的的方法。
