摘　　要：加工间隙放电状态的检测是电火花加工控制系统的一个关键环节。本文针对高速走丝电火花线切割加工 ,对放电间隙电压量的变化特性进行了理论分析和试验研究 ,提出了一种“变阈值电压法”的检测方法 ,经试验证明该方法可较好地对高速走丝电火花线切割加工中间隙状态进行检测。Precisely monitoring the gap condition is important for the machine control system to maintain a stable and high efficient machining process. In this paper, a new monitoring method was reported based on theoritical analysis and factor experiments, which was to study the characteristics of the gap voltage of wire electrical discharge machining with high travelling speed. Experiments results show that the method can real-time monitoring the gap condition well.
