Manufacturing sectors demands the use of optimization techniques to obtain the best manufacturing conditions, which is an essential need for industries towards manufacturing of quality products at lower cost. The present experimental study deals with the optimizing the set of process parameters on wire electrical discharge machining (WEDM) on Inconel 925 super alloy and multiple performance characteristics of Material removal rate, surface roughness and kerf width are identified by using Grey relational analysis (GRA) to show the impact of machining parameters on WEDM for disparate Inconel 925. Initially the metal is machined on WEDM. Machining parameter namely pulse on time, pulse off time, peak current and servo voltage on the material is noticed in Inconel 925. A Face centred composite design (CCD) of Response surface methodology (RSM) has been pre-owned for experimental work. The optimal process parameters are find out by using grey relational analysis (GRA) and confirmation test was conducted. A number of trial runs were carried out for identifying better material removal rate (MRR), kerf width (k) and surface roughness (Ra).
