Surface finish plays a critical role in increasing productivity in the machining industry and thus has important economic value. With the increasing demands of high surface finish and machining of complex shape geometries conventional machining process are now being replaced by non-traditional machining processes. In this regard surface roughness and kerf width are of crucial importance in the field of machining processes. The experiment summarizes the Taguchi optimization technique, in order to optimize the cutting parameters in Wire EDM for High Carbon High Chromium (HCHCR) Steel. The objective of optimization is to attain the minimum surface quality simultaneously and separately. In this present research work HIGH CARBON HIGH CHROMIUM STEEL (HCHCR) steel will be used as a work piece, Molybdenum wire of 0.25mm diameter will used as a tool. The input IPOL fluid will be used as a dielectric fluid. This research applies Taguchi’s design of experiment methodology and ANOVA (in MINITAB17) for optimization of process parameters. Experiments have been carried out based on L9 orthogonal array design with three process parameters namely pulse on time, pulse off time and amp current for machining time and MRR.
