Multi response Optimization of Wire EDM Process Parameters

Abstract

The paper presents the multi-response optimization of wire electrical discharge machining process. In this work the experiment has been conducted considering the four process parameters such as pulse-on-time, pulse-off-time, servo voltage and wire tension. The machining has been performed on D3 die steel using brass wire as an electrode. The cutting speed and surface roughness has been considered as process response. Taguchi based DOE has been adopted for design of experiment. The process parameter were optimized using MOORA approach for obtaining higher cutting speed and lower surface roughness.
