Abstract

Ti-6Al-4V is a titanium alloy used in aerospace industry because of its high strength, low elastic modulus and corrosion resistance property. Its hardness makes it a necessity to use non-conventional processes for machining. To analyze the effects of peak current, pulse-on time and pulse-off time on output parameters we drilled a hole of Ø 6 mm using copper (99%) electrode by Electric Discharge Machining (EDM) process. Effect of various input parameters on output viz material removal rate (MRR) and electrode wear rate (EWR) is studied. Response surface methodology was used for optimization of the process. Taguchi L9 orthogonal array was used to design the experiment. Significance of individual parameter was obtained by ANOVA. The result obtained will be compared with that obtained by grey-relational analysis.
