In the current investigation, a multi response optimization technique based on Taguchi method is planned for wire-EDM operations on aluminium alloy6063. Experiments have been performed with four machining variables: pulse-on time, pulse-off time, peak current and spark voltage. Experimentation has been planned as per Taguchi technique. Three performance characteristics namely material removal rate (MRR), surface roughness (SR) and gap current (GC) have been chosen for this study. Variation of performance measures with process variables was modeled by using response surface method.

Keywords: Wire EDM, Taghuchi’s Technique, ANOVA, MRR,SR.
