OPTIMIZATION OF PROCESS PARAMETERS IN ELECTRICAL DISCHARGE MACHINING PROCESS BY USING TAGUCHI METHOD

The objective of this research study is to investigate the optimal process parameters of Electric Discharge Machining on RENE80 nickel super alloy material with aluminum as a tool electrode. The effect of various process parameters on machining performance is investigated in this study. The input parameters considered are current, pulse on time and pulse off time are used for experimental work and their effect on Material Removal Rate, Tool Wear Rate and Surface Roughness. The Taguchi method is used to formulate the experimental layout, ANOVA method is used to analysis the effect of input process parameters on the machining characteristics and find the optimal process parameters of Electric Discharge Machining. The results of the present work reveal that proper selection of input parameters will play a significant role in Electric Discharge Machining
