EDM or electric discharge machining is achieved when a discharge take place between two points of the anode and cathode, the intense heat is generated near the zone melts and evaporates the materials in the sparking zone. For improving the effectiveness of the process, the workpiece and the tool are submerged in a dielectric fluid (hydrocarbon or mineral oils). The proposed research is workout on machining of EN36C STEEL and there parameters such as tool dia, peak current, pulse on time, and pulse off time. It is observed that consider parameter namely tool diameter and pulse off time have significant effect on performance parameters and it was also justified by ANOVA analysis. For the validation of result confirmation test has been carried out and the associated error in the context of SR is only 1.14%, MRR 5.85%.
