目前 ，脉冲电化学加工主要集中在脉冲电解成形加工方面，加工精度是其重点研究对象[1～ 7] 。日本学者用成对电极的方法对线切割加工后的表面进行光整加工[8] ，取得了较好的表面质量，但这种方法也采用成形加工，通用性较差。

The current signals were gathered in the tests, and processed by wavelet package transform. A characteristic vector was constructed by the energy of different frequency segment, which was calculated by using the coefficient of wavelet package transform of the current signals. The vector shows that the energy of low frequency segment is of the majority of the total energy, and becomes larger as the interelectrode gap decreasing.
