Abstract

The aim of this research work is to find the optimum combination of input process parameters such as peak current (IP), open voltage (Vg), pulse-on-time (Ton) and duty factor (τ) for machining of Inconel 718 on EDM. The output response parameters studied were metal removal rate (MRR), electrode wear rate (EWR) and surface roughness (Ra). L16 orthogonal array of input parameters was created as the design of experiments (DOEs) with the help of Minitab software. Grey relational analysis (GRA) method is used to get a single domain of multiple output response parameters. After that Taguchi optimization method was applied to find out the optimal parameter setting for higher MRR, lower TWR and lower Ra.
