摘　　要：利用正交试验设计的方法,对高速走丝电火花线切割加工中的峰值电流、脉冲宽度、脉间比和零件加工厚度等工艺条件进行了试验的优化设计.运用综合评分法对零件的加工速度和表面粗糙度进行了综合考虑,将多目标问题转化成单目标问题.考虑到线切割加工的非线性特点,利用二元表找出了交互作用下的各种因素的最佳水平.得出了电参数与加工速度和表面粗糙度之间的联系,为进一步研究电火花线切割加工工艺规律提供了基础.This paper uses the orthogonal experimental design method to optimize the technological parameters,which include peak pulse current,pulse width,inter-pulse ratio and parts thickness of the high-speed WEDM.By using the comprehensive scoring method,synthetically considering the machining speed and surface roughness,the multi-objective problem is transformed into single-objective problem.Considering the non-linear characteristic of WEDM,we use the dual element table was used to find the best level of all interaction machining factors.The relationship of the electrical parameters to the machining time and the roughness is acquired.This paper provides basis for advanced study of technological rule of WEDM.
