摘　　要：在分析了电火花加工放电状态电压特性的基础上,设计了放电间隙电压的检测电路,并同时设计了V/F转换电路。当加工条件稳定时,用间隙电压直接控制电机转速;当加工条件变化时,用上位机来调整电机转速,从而实现电加工的实时与稳定。Based on the analyzed the characteristics of EDM discharge states, the detection circuit of discharge gap voltage was designed. And the V/F translation circuit was designed, too. When the processing condition was stable, the rotate speed of step motor was controlled by the gap voltage. When the processing condition varied, the rotate of step motor was controlled by PC. The result of such design show that the system has high real - time and stability.
