中文摘要：

为了提高机械研磨的材料去除率，探讨了在机械研磨的界面上引入超声能的复合研磨方式，将机械研磨和引入超声的复合研磨两种方法的去除效率进行了实验对比．发现复合研磨后，去除效率有显著提高；得出超声/机械复合研磨的加工效率明显优于机械研磨。所获得的工艺规律对于工业生产具有一定指导意义。

英文摘要：

To improve the material removal rate （MRR）, this paper discussed a new ultrasonic polishing in which the ultrasonic energy was introduced to the interface of common polishing, and compared this new polishing process with the common polishing process in the MRR. It has been proved that the MRR of machining were improved greatly; The conclusion that the combining polishing is superior to mechanical polishing was reached . This paper also applies a simple analysis on the mechanism of the new coalescence process which is useful to industrial products and theory research.
