Process parameter optimization on EN8 steel in electric discharge machining (EDM) using response surface methodology (RSM) technique

Abstract

Electric discharge machining (EDM) is widely used in the manufacturing sector due to its exceptional machining attributes and high fastidiousness, which could not be accomplished via other conventional machining. The research work aims at analyzing the optimal machining parameter and to reduce the machining time by varies in an increase material removal rate (MRR) and productivity and low tool wear rate (TWR). The parameters of Peak current, Pulse on time, Di-Electric Pressure and Tool diameter are varied. The usage of variance analysis (ANOVA) optimized parameters are determined by way of doing diverse dry runs the usage of Response Surface Methodology (RSM) approach and the mistake percent can be mounted and parameter contribution for MRR and TWR have been also observed.
