摘　　要：分析了往复走丝电火花线切割在高速加工中影响电极丝寿命的主要因素,在一定电源脉冲参数且平稳切割的前提下,通过典型电极丝对不同工件厚度的切割对比和试验数据分析,得出切割厚度是影响电极丝寿命的主要因素之一。The main factors influencing the wire electrode working life of back and forth wire cutting WEDM in high-speed machining were analyzed and the definition of wire elec trode working life was proposed in this paper.Based on the comparison of various thick nesses of work pieces cut by typical wire electrode and experimental data analysis under certain power pulse parameters and stationary cutting,it was concluded that the cutting thickness is one of the main factors which influence the working life of wire electrode.

关 键 词：往复走丝 工件厚度 切割面积 电极丝寿命
