使用640A型宽带频谱分析仪,对电火花加工中放电产生的射频信号进行了频谱分析,测出了正常火花放电和异常电弧放电射频信号的频率特性和频谱分布的确切范围,并发现了不同电极材料在放电加工时产生的射频频谱存在差异的现象。
Using the 640A broadband spectrum analyzer, the frequency spectrum of radio frequency signal generated during EDM was analyzed, and the exact range of frequency characteristics and spectrum distribution of normal and abnormal arc discharge RF signals were measured. Different electrodes Materials in the EDM generated radio frequency spectrum of the phenomenon there is a difference.
