Abstract—Electrical Discharge Machining (EDM),a nontraditional machining process has been replacing drilling milling grinding and other traditional machining operations and is now a well-established machining operation in many manufacturing industries throughout the world. Modern ED machinery is capable of machining geometrically complex or hard material component. The experimental investigations were carried out to study the effect s of dielectric mediums and pulsed current on MRR, Diametrical over cut, Electrode wear and surface roughness when machining MONEL 400(tm).In this investigation were need different dielectric mediums like kerosene, paraffin, EDM commercial grad oil and also kerosene+servotherm oil.

Index Terms—EDM, Diameteral overcut, Electrode wear, Surface roughness, Electrode materials, Dielectric mediums
