Abstract

Among the thermal mode of machining, electrical discharge machining (spark erosion machining) is mainly a method for the manufacturing of a multitude[1] of ever changing geometries very often produced as unit job or in small batches.The basic concept of El ectrcal Discharge Machining (EDM) process is creating out of metals affected by the sudden stoppage of the electron beam[3] by the solid metal surfaces of the anode.The portion of the anode facing the direct electrical pulse reaches the boiling point.Even in case of medium long pulse the rate of temperature increases in tens of millions of degree per second which means dealing with an explosion process.In the present work, a combined optimization approach is used for the estimation of maximum metal removal rate(MRR) [5]and minimum tool wear rate(TWR), surface roughness(SR) and overcut(OC) of produced in electrical discharge machining. The important input parameters current (I), pulse on time (Ton), pulse off time (Toff) and voltage (V ) are considered.
