电火花线切割加工中极间间隙击穿规律的研究

摘要

For the question of difficult to control discharge process between the electrodes in WEDM,systematic analysis of the relationship breakdown and the distance between poles, the relationship of the breakdown voltage and pulse duration, the relationship breakdown and impurity,the relationship breakdown and the temperature were did, the WEDM in the general laws of the electrode gap breakdown was summed up with better control of WEDM process in the very room to provide a theoretical basis for discharge.%针对电火花线切割加工中极间放电过程难以控制的问题,系统分析了击穿与极间距离、击穿与脉冲电压持续时间、击穿与杂质、击穿与液体介质温度等关系,总结出了电火花线切割加工中电极间隙击穿的一般规律,从而为更好地控制电火花线切割加工中极间放电过程提供了理论依据.
