Experimental Study of Various Input Parameters for Electric Discharge Machining

Abstract

This study presents analysis of different parameters of EDM. In this work four parameters Current, Tool, Workpiece and Pulse On time are varied. L18 orthogonal array is used. MRR, TWR and surface roughness are calculated after experiments. F test is applied and plots for MRR, TWR and SR are constructed. In this study the tool comes out factor which has maximum effect on all three outputs. The current comes out to be second most important factor. Value of current is directly proportional to MRR, TWR and SR. The work pieces are mainly significant in Surface roughness.
