During the process, high material removal rates are obtained while the toolelectrode wear is extremely small and the sub-surface is not damaged.
通过这个过程，当工具电极(阳级？)只有极小的损耗时材料便获得了了迁移速度，并且并不危害副表面。
2
The laws of material remove rate with toolelectrode ultrasonic vibration assisted are less than that with workpiece ultrasonic vibration assisted.
实验结果表明：工具电极做超声振动时的材料去除率比工件做超声振动时的材料去除率要小；

In electric discharge milling machining (EDMM) process, the rotation of the toolelectrode makes tool wear be axial symmetrical distribution, so it is possible to be compensated.
