Abstract

New developments in the field of material science have led to new engineering metallic materials, composite materials and high-tech ceramics, having good mechanical properties and thermal characteristics also sufficient electrical conductivity so that they can readily be machined by spark erosion. At the present time, Electrical discharge machine (EDM) is a widespread technique used in industry for high-precision machining of all types of conductive materials such as: metals, metallic alloys, graphite or even some ceramic materials. In this paper experimentation on EN-31 material with Copper as Electrode material using EDM is proposed. Various Process parameters namely Discharge Current (DC), Pulse on Time,Pulse off Time etc. have been considered. The process performance is measured in terms of Response variable like Tool Wear. Number of experiments conducted is based on Taguchi method using L9 Orthogonal Array with three level and three factors. The aim of the present study is to investigate the variation of Tool wear with the varying machining parameters (Ton, Toff and discharge current) in die sinking EDM. Variation of responses with respect to each input machining parameter is presented and analyzed. This study shows that in case of tool wear, discharge current (DC) is the effective parameter after that the Pulse on Time and the Pulse off Time are having less effect on tool wear
