Research of LS-WEDM Finishing in Gas Based on Gray Relation Grade

Abstract:

Authors have presented a new procedure as gas-liquid combined multiple cut. In order to acquire the best machining quality and the greatest efficiency, it is necessary to analyze the WEDM process with multiple performance characteristics including machining time and surface roughness and to optimize some processing parameters such as pulse duration, pulse interval, peak current, main power supply voltage, servo feed, offset and servo voltage. The orthogonal experiment is designed to reveal the relationship among the parameters, the gray relevance theory is used to optimize the processing parameters under the multiple process index of the LS-WEDM in gas, namely optimizing the process parameters under the surface roughness and machining time, and the optimized process parameters can be obtained from gray relation grade.
