INTRODUCTION Surface modification is a miraculous application of Electric Discharge Machining (EDM). It can modify the conductive material surface by both removing material from the surface and depositing material on the surface. It can remove or deposit material from the work surface through controlled electrical sparks by the process of melting and evaporation. The controlled sparks erode material from the work and tool surface within very short intervals of time. Study of surface morphology widens
