Parametric optimization for maximization of MRR in WEDM of D2 steel material

Abstract

The present work is planned to optimize the material removal rate (MRR) in wire electrical discharge machining (WEDM) of D2 tool steel. Machining parameters namely pulse on time, pulse off-time, voltage gap and wire feed have been chosen for the present investigation to perform experimental runs. The experiments have been conducted using L16orthogonal array of Taguchi method. The effects of machining parameters on MRR has been determined by utilizing signal-to-noise ratio and graphical main affects plot. The optimum parametric condition has been acquired for looking for maximizing MRR by using Taguchi method. Confirmatory experiments have also been conducted to verify the predicted parametric setting. From the present investigation, it is found that Taguchi method is robust to study, analyze and optimize processing conditions in WEDM.
