摘要:In micro-EDM machining process, the debris of materials is difficult to be removed form the discharging gap. This problem leads the instability of discharge state, and reduces the efficiency of discharge machining. A new method of PZT incentive synchronous compression discharge channel micro-EDM is developed based on the inverse piezoelectric effect of PZT ceramics, driving by a spark discharge and PZT sync pulse power. The composition of the system is described and many experiments have been done and the effects of parameters on electrode wear ratio (EWR) have been analyzed in this paper. The results indicated that increasing the voltage and width of pulse can lower the rate of electrode wear, increase the efficiency of electric-machining, while increasing the frequency of discharge pulse can lead the increasing of EWR. © (2014) Trans Tech Publications, Switzerland.
