Abstract

Scientifically emerging industries like automotive, defense, aerospace, electronics, nuclear power, metallic molds and dies require materials of high strength, high-temperature resistant alloys like carbides, super alloys, haste-alloys etc. Manufacturers strive hard to produce these components at lower cost and of esteem quality as they have a direct impact on the profit earned by the firm. Hence, the productivity can be improved by increasing the material removal rate (or) by reducing the machining time of the product. Addition of a fine conductive powder to the dielectric fluid decreases its insulating strength and consequently increases the inter-electrode space causing an easy removal of the debris.The process variables of PMEDM play a considerable role in material removal mechanism. Performance of the PMEDM process depends upon characteristics like powder type, concentration, particle size, electrode area and workpiece constituents. As a result, the process becomes more stable, thereby, improving the material removal rate (MRR) and surface finish. Moreover, the surface develops high resistance to corrosion and abrasion. In this study, we have chosen the OHNS (Oil Hardened Non-Shrinking) die steel as workpiece material. A copper electrode and brass electrode with a diameter of 10 mm were used to cut the workpiece in EDM. Commercial kerosene has been chosen as the dielectric fluid. The consequence of the Machining parameters such as Pulse ON time, Pulse OFF time and current over the Machining time and Surface Roughness has been analyzed. The interaction study is made by Response Surface Methodology.
