摘　　要：为了进一步提高低速走丝线切割的表面质量,本文采用了气液混合多次切割的工艺。并采用正交设计法研究了脉冲宽度、脉冲间隔、峰值电流、伺服电压、伺服进给速度5个因素对表面粗糙度的影响,并通极差分析和利用二元表找出了在考虑上述5个因素交互作用下各因素的最佳水平,为进一步研究低速电火花线切割加工工艺提供了基础。In order to further improve the surface quality in LS--WEDM, a new procedure as Gas-liquid Combined Multiple Cut is presented. Orthogonal experimental design method were used to study Effects of pulse duration, pulse interval, peak current, servo voltage and servo feed on roughness in finishing in gas, By range analysis and the binary table the optimum level of the above five factors was found in consideration of the above five factors interaction. The paper provides the basis for advanced study of finishing process of LS--WEDM.
