Abstract

The Electrical Discharge Machine (EDM), parameters are investigated during the machining of Inconel 825 by using different tool geometry of zirconium copper electrode. Demand for better MRR, SR, and lower Tool Wear Rate are increasing recently for all materials, the low rigidity and high material removal rate of Inconel alloy offers a challenging task in obtaining output responses. The analysis of output responses such as Metal Removal Rate (MRR) of Inconel 825 material is carried out an excellent result can be obtained by using Taguchi L16 Orthogonal Array under different conditions of Parameters. The response of MRR is considered for improving machining efficiency. Optimal combination of parameters was obtained Taguchi optimization technique. The confirmation experiments results shows that the significant improvement in output responses was obtained. ANOVA have been used to analyze the contribution of individual parameters on Material Removal Rate. The experimental result demonstrates that the Taguchi method satisfies the practical requirements.
