Abstract

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