     The experimental investigation of Material removal rate (BRR), and Tool wear rate (TWR) during machining of 80%Sn-14%Ni-6%Cu using EDM was studied in this paper. The input parameters include current (I), Pulse ON time (Ton), Voltage, Flushing pressure were used for experimental work. A well-designed experimental scheme was used to reduce the total number of experiments. The results of analysis of variance (ANOVA) indicate that the proposed mathematical model can be adequately describe the performance within the limit of factors being studied. The optimal set of process parameters has also been predicted to maximize the MRR and minimize the TWR.To optimize the machining parameters of EDM on 80%Sn-14%Ni-6%Cu by using the Response Surface Methodology(RSM), Box-behnken Design(BBD) and ANOVA methods. It can be observed that Current has the largest effect on the material removal rate.The Pulse ON has the smallest effect on the MRR.
