Electrical discharge machining (EDM) is a non-traditional manufacturing technique that has been widelyused in the production of precision engineering components throughout the world in recent years. The most importantperformance measure in EDM is the MRR and TWR. In this study, the experimental studies were conducted undervarying pulse on time, current and electrode diameter. The numbers of experiments were conducted by L18 orthogonalarray of Taguchi’s methodology. Signal-to-noise (S/N) ratio was employed to determine the most influencing levels ofparameters that affect the MRR and TWR in the EDM of AISI P20 tool steel. To validate the study, confirmationexperiment has been carried out at optimum set of parameters and predicted results have been found to be in goodagreement with experimental findings. ANOVA find the influence of parameters in the experiments.
