Abstract

Inconel 718 super alloy are highly used in gas turbine, space vehicles, aircraft, nuclear reactors, submarine, petrochemical equipments and other high temperature applications. Due to the excellent mechanical properties, high strength at elevated temperature, it’s hard to machine in traditional machining process. EDM is one of the most suitable techniques to shape this alloy into desire shape. The present study is to investigate the machining characteristics of Inconel 718 material on CNC—EDM using copper and graphite electrodes. Taguchi L9 orthogonal array had been used for design of experiment, where the input parameters are current, Pulse-ON, Pulse-OFF and the experimental outcomes are material removal (MRR). Analysis of variance (ANOVA) is employed to indicate the level of significance of machining parameters.
