Parametric optimization of Electric Discharge Machine using Response Surface Method

Abstract

Present work has been done for the parametric optimization of process parameters such as discharge current, pulse on time, gap voltage and duty cycle on a Electric Discharge Machine for high speed steel for getting maximum material removal rate and at the same time to get minimum surface roughness. Experiments has been performed an a matrix formulated by Response Surface Method and further analysis work has been done by using regression test and ANOVA to get the optimized range of parameters to get the desired results on EDM machine.
