摘　　要：分析了线切割加工表面变质层的影响因素,在采用和真实加工相类似的边界条件下,用有限元软件ANSYS对线切割加工过程进行温度分布计算,模拟电参数(脉冲宽度)的变化对线切割加工齿轮工件表面变质层的影响,得出在实验条件下,按DK7732机床各档脉冲宽度加工齿轮时变质层的分布数据,以利于后续的工艺探究。同时提出了减少变质层的相应措施。The influence factors of surface deformation layer in WEDM is analyzed,and in the use of the boundary conditions similar to actual processing,Calculation of the temperature distribution during WEDM based on ANSYS software is carried out,to simulate the influence of the change of electrical parameters（pulse width） on surface deformation layer of gear in WEDM.The data about the distribution of surface deformation layer of gear in processing by DK7732 machine pulse width of each stall under the experimental conditions is obtained.In order to facilitate of the research of follow-up process.At the same time,the corresponding measures to reduce surface deformation layer is proposed.
