Electrical discharge machining (EDM) process is convert electrical energy into heat energy between the work piece and tool electrode in the presence of dielectric fluid like, EDM oil, to process conductive difficult-to-machine materials. EDM process is has been applicable in the machining of hard, brittle and all kinds of electric conductive materials. This process widely used for produces die making, mould making, complex shapes, deep holes and other geometrical shapes as per desire. Inconel 600 super alloy materials widely used in various types of industries such as: aerospace, aircraft, nuclear, food processing, pulp manufacturing, automobiles industry etc. In this study, investigations on the effect of process parameters on machining of Inconel 600 super alloy material. Tungsten carbide material used as tool electrode and EDM oil used as dielectric fluid. The effects of input process parameters such as pulse-on-time, peak current and gap voltage on performance measure material removal rate was investigated using Taguchi method. MRR is lineally increases with the increase in peak current during the EDM process. MRR is increases with the increase in gap voltage. Initially MRR increases with increase in pulse on time then decreases with the increase of pulse on time.
