In the present study, the performance parameters of EDM process are to be evaluated to achieve the feasibility in machining of H13 tool steel which has wide application in the Hot punches and dies for blanking, forging, swaging and bending, Nozzles for aluminum, tin and lead die casting, Hot extrusion dies for aluminum, cores ejector pins, inserts, Hot shear blades. The important process parameters that have been selected are peak current, pulse on time and pulse off time. The outputs responses are material removal rate (MRR), electrode wear rate (EWR) and surface roughness (SR). Here the machining is done by EDM using two different electrodes like Copper, and Bronze and investigate which type of electrode gives better result for increasing MRR, decrease SR and lower EWR. The experiments were planned, conducted and analyzed using Response surface methodology and analysis of variance (ANOVA) has been applied to identify the significant process parameters.
