The objective of this work is to investigate the effect of three process parameters, namely Peak Current, Pulse On-Time and flushing pressure on Metal Removal Rate (MRR) and Surface Roughness (SR) during electrical discharge machining of EN-5 mild steel. It have widely applications like in making die, shafts, racks, pinions, studs, bolts, nuts, rollers etc. A copper tool of diameter 5 mm was used to drill the specimens. An L9 orthogonal array (OA), for the three machining parameters at three levels each, was opted to conduct the experiments. The ANOVA analysis indicates that the percentage contribution of peak current, Pulse On-Time and flushing pressure
