In this present era, Aluminium Matrix Composites are the most hopeful alternatives to many industrial and structural applications because of their good parental and inbuilt mechanical properties. This work deals with the machining of stir castAl6061 matrix reinforced with 6 wt% zinc oxide particle sample by Wire cut Electro Discharge Machining and investigate the effects of input factors such as pulse on time, wire feed rate and voltage over the responses metal removal rate (MRR) and surface roughness. Wire EDM machining is carried out with a varying pulse on time (4–6 µs), Voltage (50–80 V) and wire feed rate (2–6 m/min). By using TOPSIS approach, the optimal machining parameters are recommended. The optimized results suggest that higher MRR and lower surface roughness were accomplished with the combination of pulse on time, voltage and wire feed rate at 6 µs, 50 V and 4 m/min respectively. The machined surfaces are analyzed by an optical microscope. The significant factors and the effect of factors over responses are determined and analyzed by using ANOVA approach. The results attained are useful for the manufacturers to obtain the better WEDM machining of Al6061 reinforced with ZnO particles.
