With the increasing demands of high surface finish and machining of complex shape geometries, conventional machining process are now being replaced by non-traditional machining processes. Wire Electric Discharge Machining (WEDM) is a non-traditional process of material from conductive material to produce parts with intricate shape and profiles. Machining parameters affecting quality characteristics in the machining process is thoroughly studied. Productivity is constantly a matter of concern with a high level of accuracy for any process; rather it is the driver of economic growth of industry. The problem like lower production, higher surface roughness, due to higher tool wear, cutting wire have to change many times also facing vibration problem. Surface roughness and MRR are of crucial importance in the field of machining processes. The input parameters selected for optimization voltage, pulse on time, and current. Dielectric fluid pressure, wire speed, wire tension, resistance and cutting length are taken as fixed parameters. For each experiment surface roughness and MRR was determined by using contact signal to noise ratio measuring system respectively. By using multi objective optimization technique GRA and ANOVA, the optimal value is obtained for surface roughness and MRR and by using Taguchi optimization technique, optimized value is obtained separately. The objective of optimization is to attain the minimum SR and the maximum MRR.
