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

在电火花铣削加工中，由于工具电极作旋转运动，其损耗呈轴对称分布，使工具电极的补偿成为可能。

The experiment used electrode with different rotation speed to process deep-small holes, and collected the time data during the whole process, after this more of the processing curves could be formed.

采用不同旋转速度的电极进行电火花深小孔加工，通过采集加工时间数据，得到多条加工曲线。
