This paper discuss on the optimization of process parameters for the machining of Al6061 aluminium alloy in Wire Electrical Discharge Machining (WEDM). Al6061 has a significant use in various domains like aerospace, ordnance, and automotive sectors. Wire EDM is used in the fields of Dies, Moulds Precision Manufacturing and contour cutting. The experiments have been conducted by varying four process parameters such as Peak current, Ton, Toffand Servo feed in three different levels. The important output measurable parameters like material removal rate (MRR), Surface roughness (Ra) value of the machined surface for each experimental runs has been measured. Taguchi’s L9(34) Orthogonal Array was employed to carry on the experiments, that agree with arbitrarily opted distinct combinations of the mentioned process parameter. All experiments have been conducted using Electronica Sprintcut WEDM. Grey relational analysis was employed to change over the multi-objective measure into a tantamount individual objective function. Taguchi technique was used to optimize the overall grey relational grade. Verification experiments were done to validate the optimal results.
