Comparison of machining characteristics of Inconel 601 with normal and cryogenic cooled electrode in EDM using RSM

Abstract

In today's world cryogenic cooling is used in various fields to increase the physical and mechanical properties of the materials. It is used in various ways such as fuels for rockets, frizzing food and transporting it to different locations, storing rare blood groups, giving chilling and other special effects in nightclub etc. In this paper, we will compare the effect of normal copper electrode and cryogenically cooled copper electrode in Electric Discharge Machine (EDM) process with Inconel 601 as work piece. Peak current, gap voltage and pulse on time are the different input parameters and MRR, surface roughness and TWR are the output parameters for the process. The experimental work is done using Box-Behnken Design (BBD) in Design of Experiment (DOE). Further, the optimize result for variation of output parameters with change in input parameters is seen by using Analysis of Variance (ANOVA)and Response Surface Methodology (RSM). The paper will tell us about the effect of normal and cryogenic cooled electrode on Inconel 601 on EDM.
