Electrical discharge machining (EDM) is non-traditional machining processes. EDM process is based on thermoelectric energy between the work piece and a tool electrode. A pulse discharge occurs in a small gap between the work piece and the tool electrode and removes the unwanted material from the material through melting and vaporizing. The present work aims to study the effect of EDM input parameters like pulse on time, pulse off time and current on the performance measure like Electrode wear rate (EWR) and over cut during electro discharge machining of AISI D3 steel as work piece and copper-silver alloy as electrodes. Taguchi method will be employed for experimental work .The research work is expected to find out the best material that will lead to a minimum over cut and minimum (EWR). The design of experiments is based on Taguchi’s L9 orthogonal array.
