序言从电火花加工方法被采用以来,至今还没能建立起一个公认的计算公式。使电火花加工工艺和设备,包括电源和伺服控制系统的改进至今都只能凭经验进行研究。在电火花加工中,独立式脉冲电源能独立地改变参数,很好地满足电极对电参数的要求。采用独立式脉冲电源之后,粗加工时电流相当稳定。但好的加工结果不仅取决于好的 Preamble Since the EDM method has been adopted, so far failed to establish a recognized formula. So far, EDM processes and equipment, including power and servo control system improvements can only be empirically studied. In EDM, independent pulse power supply can independently change the parameters, to meet the electrode parameters of the electrical requirements. After using a stand-alone pulse power, roughing current quite stable. But good processing results depend not only on good ones
