EDM is very unique process because of its ability to machine almost every material for which conventional machining is not possible along with surface finish (SF). Electrical discharge machining is used for manufacturing of the components where excellent surface finish is required. But the major limitation of the process is that the Material Removal Rate (MRR) is very low. To increase the MRR Powder Mixed EDM (PMEDM) is one of the recent advancements in EDM process where the ceramic powder particles added to the dielectric fluid. The material removal rate (MRR) needs to be increased along maintaining the surface finish (SF) as higher productivity levels are demanded, which is today's need in industrial area. For this we are going to add different ceramic powder particles in the die electric fluid after the optimization of conventional EDM parameters. This work will be carried out on Inconel 718 which is Nickel alloy which gives very wide temperature range for the application.
