Electric Discharge Machining (E.D.M) is a non-conventional machining process and has a larger extent of application in the manufacturing industry due to its accuracy. E.D.M simply uses an electrical spark between the workpiece and tool in the presence of medium dielectric to erode the workpiece in a controlled manner. This study investigates the enhance the various performance parameters measured in E.D.M process using Tagushi Technique. The main goals are to maximize the removal rate of material M.R.R and minimizing the wear rate of tool TWR.
