Electro Discharge Machining (EDM) is a non traditional machining process, based on thermo electric energy between the work piece and electrode. In this process, the material removal is occurred electro thermally by a series of successive discrete discharges between electrode and the work piece. Electro Discharge Machine which has the ability to machine hard, difficult to machine material and parts with internal complex shape by using precisely controlled sparks that occurs between electrode and work piece in the presence of dielectric fluid. This spark removes material from both work piece and electrode. Material Removal Rate (MRR) is of crucial importance in this process. In this research experiment has been done along with Copper and Graphite tool material as well as Mild Steel and Aluminium material has been used as work piece. Three major Control Parameters named as Electrode Speed (V), Current (I) and Depth of Cut (h) are considered to determine their influence on MRR. In this experiment three levels of each parameter has been taken and an analysis has been made to find out the influence of control parameters on MRR using S N Ratio and ANOVA Analysis.
