摘　　要：针对短电弧铣削加工过程中出现的电弧响应速度慢、频繁短路、拉弧等与间隙放电特性有关的问题,采用对加工间隙进行放电波形采集、提取、分析以及对间隙放电状态进行分类的方法,进行间隙放电特性的研究。实验结果直观地反映了不同放电状态下间隙放电波形和加工效果的差异,为改善加工效果提供了参考。In order to solve the problems related to the characteristics of gap discharge in the process of short electrical arc milling,such as slow arc response,frequent short circuit and arc prolong,the gap discharge characteristic was studied by collecting,extracting and analyzing the discharge waveform and classifying the gap discharge state.The experimental results directly reflect the difference of the gap discharge waveform and the machining effect in different discharge states,which provides reference for improving the machining effect.
