Multi-Objective Optimization of Processing Parameters in WEDM with Stainless Steel-304 for Die-Angular Cutting

This paper is focusing on the improvement of the accuracy of WEDM process for machining the precision-die angular stainless-steel parts. The controllable parameters are studied and analyzed by using Response Surface Method technique with respect to the responses of dimensional accuracy and surface quality. Then, these models are optimized by using the multi-objective optimization technique to realize optimal processing parameters. These optimal controllable parameters are ready for WEDM operating technicians’ use.
