Analysis of PMEDM Parameters for the Machining of Inconel-800 Material Using Taguchi Methodology

Abstract

In the present scenario, copper tools and Inconel-based materials became popular due to their unique properties and are widely used for manufacturing various materials, airplane parts, furnace parts, etc. That is why, copper as a tool and nickel-based superalloy as a material, we have chosen for further experimentation. In order to study behavior of Inconel material, the content material removal rate (MRR) has been selected as a response parameter. After reviewing the literature, the process parameters, i.e. current, pulse on time (Ton), pulse off time (Toff), and electrical discharge machining (EDM) have been chosen for the experiment. After analysis, results indicated that, the peak current more effect the MRR as compared with the other two process parameters, i.e. Ton and Toff.
