Analysis on electrochemical discharge machining during micro-channel cutting on glass

Abstract

Modern industrial field of micro-machining has an attractive attention to increase the machinability of electrically non-conducting materials. Electrochemical discharge micro-machining process has the ability to machine high strength non-conducting brittle materials like glass. This paper shows a development of second-order correlation between the various machining criteria and different process parameters such as applied voltage, electrolyte concentration and inter-electrode gap (IEG). The analysis of variance (ANOVA) has been performed to find out the adequacy of the developed models. The research paper includes the effects of various process parameters on material removal rate (MRR), overcut (OC), heat affected zone (HAZ) and machining depth (MD) during micro-channel generation on glass. This paper also represents the single as well as multi-objective optimised results to determine the suitable parametric combination for maximum MRR and machining depth and minimum overcut and HAZ area using response surface methodology (RSM) and genetic algorithm (GA).
