Abstract
In order to further improve the surface quality in LS-WEDM, a new procedure as Gas-liquid Combined Multiple Cut (the finishing is in gas) is presented and has carried on the contrast experiment to conventional WEDM multi cutting processing in the paper. the single factor and 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, analysis of variance 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 basis for advanced study of finishing process of LS-WEDM.
