Electric Discharge Machining is a non-conventional machining process, used to machining difficult to machine materials. The major problem faced while doing EDM is high tool wear rate, end wear, corner wear , surface roughness and low material removal rate,. In this research work experimental investigations have been made to find the machining characteristics of high density ultra fine graphite and Inconel 718 superalloy. The present paper presents the effects of peak current, pulse on-time(Ton) and duty cycle on the output parameters like Material Removal Rate(MMR, End Wear and Surface Roughness(SR).
