摘　　要：分析了微细孔电火花加工脉冲识别,提出以间隙平均电压、火化率偏差和火化率偏差变化为模糊控制器的3个输入控制参数,建立了微细孔电火花模糊控制加工策略,同时比较说明了模糊控制器对微孔电火花加工性能影响,实验结果说明模糊控制器对微细孔电火花加工系统更为有效,加工过程更加平稳.On the basis of analyzing the recog- nition of EDM pulses, three input parameters such as average gap voltage, deviation in spark ratio, and change in the deviation in spark ratio is presented for the fuzzy logic control. With it, a new fuzzy controller is designed and experimental results show that the fuzzy logic EDM control system yields a much more stable and efficient micro - hole EDM drilling process.
