Multi Response Optimization of Powder Additive Mixed Electrical Discharge Machining by Taguchi Analysis

Abstract The material removal rate needs to be maximized while controlling the surface quality as increasing quality demands, at higher productivity level which is today's need in industrial area. Powder Additive mixed EDM brings the revolution in machining industry due to high surface finish and high MRR. Many research works has already done to analyse the effect of powder mixed dielectric on EDM machining process. In this paper, a study was carried out on the influence of the parameters such peak current, powder type, powder concentration on EN-19 work piece. Taguchi methodology has been adopted to plan and analyze the experimental results. In this study seven factors with three levels are investigated using Orthogonal Array (OA) L9. The result of the experiment then was collected and analyzed using MINITAB 13 software. The recommended best parametric settings have been verified by conducting confirmation experiments for MRR.
