Experimental study and analysis on generating contour feature on Inconel 625 using Micro-EDM

Abstract

An experimental investigation into the generation of contour features on Inconel 625 utilizing Micro Electrical Discharge Machining (Micro EDM). The primary focus is optimizing crucial process parameters, namely pulse off time, pulse on time, and current, to enhance machining efficiency and quality. The study employs a systematic approach to explore the impact of varying gap voltage and current on the Micro EDM process. The optimization seeks to reduce surface roughness, one of the main variables affecting the overall performance of the machining process, through a series of carefully designed experiments. The experimental results will be systematically analyzed to establish correlations between process parameters and machining outcomes. The optimum values obtained from the RSM technique for current, pulse off, and pulse on time are 3 amp, 7.23µ sec, and 6.83µ sec, respectively.
