摘要

Electric Discharge Machining (EDM) is one of the nontraditional machining processes used to produce critical shape on hard or brittle conductive materials and it can also besuccessfully applied on materials that are extremely difficult-to-machine using traditional machining processes. In this experimental analysis the optimum machining parameters areestimated using Taguchi based method for EN24 steel which have wide range of application in aircraft, automotive and general engineering applications for example- propeller or gearshafts, connecting rods, aircraft landing gear components. Influence of various parameters on MRR and Surface roughness of EN24 steel has also been investigated in this analysis. Taguchi methodology with L9 orthogonal array was used to optimize specified parameters such as; current, pulse on time and flushing pressure Grey relational technique is used to convert multiobjective to single objective. Finally ANOVA concept is employed on multi SN ratio to find out the relative significance of machining parameter. It is found that current has maximum significance of 44.867% on response parameters. Current at 5Amp, pulse on time at 50 μs and flushing pressure at 0.6 Kg/m2 bears the optimal levels for MRR and SR combinedly.Cite this ArticleTanmay Jyoti Deka, Asit behera, KamalK. Joshi.
