Abstract : Wire electrical discharge machining has become an important non-traditional machining process, as it provides an effective solution for producing components made of difficult-to-machine materials like tungsten carbide, titanium, zirconium etc., and intricate shapes, which are not possible by conventional machining methods. This research paper deals with Response Surface Methodology approach for maximizing the material removal rate in wire electrical discharge machining. The investigated machining parameters were wire tension, pulse on time and peak current. Machining was carried on AISI D2 cold work steel, which is widely used in die and mold making industries. The experiments were designed based on response surface design method; in which central composite design method was applied for fitting the second order model. After the experimentation, the effect of the parameters on MRR was determined by analysis of variance (ANOVA). Also the interaction of their parameters was considered for their significance. Regression analysis was done and a second order mathematical model was fitted for MRR considering the parameters and their significant interactions. And at last optimization was carried using desirability approach and confirmation experiments were performed.
