Abstract
The present work attempts to assess the best parametric combination that satisfies multiple objectives of minimization of tool wear and surface roughness and maximization of material removal in electric discharge machining (EDM) of D2 steel. The study specifically focuses on influence of tool electrode material on machining performance. An electrode prepared by direct metal laser sintering (DMLS) has been chosen along with conventional electrodes like copper and brass to assess the feasibility of substituting the conventional electrodes with DMLS electrode which is a novel method. Very few attempts are being made to compare the performance of conventional electrodes with the electrodes prepared by non-conventional method. The study makes use of utility concept-based Taguchi method. Utility concept first finds out the overall utility index (OUI) which is a representative index of all the objectives considered in the study, and then, the problem can easily be solved by Taguchi method.
