Abstract

Among the different non-traditional machining practice wire electrical discharge machining (WEDM) is the most flexible, useful and high précised machining process which is used to machine conductive materials. Presence of several contradictory responses in WEDM makes it difficult to choose the optimum machining parameter setting. This research demonstrates a multiple-criteria decision analysis (MCDA), desirability function analysis to optimize key input parameters for some contrary outputs during WEDM of inconel 718. Several significant machining variables, like pulse on time (TON), pulse off time (TOFF), pulsed current (WF) and servo voltage (SV) were considered as machining inputs for this investigation. The selected WEDM outputs are kerf width (KW), material removal rate (MRR) and root mean square roughness (Rq). The ideal input setting for multi-performance features has been found as TON = 120 µs., TOFF = 53 µs., I = 210 A. and SV = 25 V. The current research concentrated on the application of MCDA desirability function analysis as a precarious selection approach to deal with multi criteria optimization atmosphere.
