摘　　要：短电弧加工(SEAP)是解决特硬、超强、高韧性等难加工材料的表层去除加工难题的有效手段。介绍了短电弧机床电流信号采集系统的结构组成和工作原理,对该系统进行了SEAP电流信号的采集以及电流波形变化规律的初步分析。另外,还介绍了该系统对采集的信号进行滤波处理的两种方法:数字滤波器滤波及小波变换滤波。Short electric arc processing is the effective means for solving the difficult problem of processing the machining materials which have the characteristics of great rigidity, intensity and tenacity. This paper introduces the structure and the working principle of the SEAP system which accomplishes the collection of electricity signal and the preliminaly analysis of wave transformation rule. Besides, it introduces the methods of digital filter and wavelet transform which uses this system to can＇y through the waves from the collected signal.
