In the present work, micro-electric discharge machining (micro-EDM) of Ti-6Al-V alloy with tungsten carbide electrode has been performed. Ti-6Al-4V, which is difficult to machine via conventional machining techniques, however, can be easily machined via EDM machining, with careful selection of machining parameters for getting optimum results. In this study, the effect of various input parameters; current, voltage, frequency, and width, on output parameter viz., metal removal rate (MRR), tool wear rate (TWR), and overcut (OC) are studied. Grey relational analysis and analysis of variance (ANOVA) have been performed to optimize the levels of input parameters.
