Abstract

This paper aims to perform an experimental study of drilling micro-holes on titanium grade 2 alloy using micro-electrical discharge machining (µEDM) process. Key process parameters such as capacitance, feed rate (FR) and tool rotation speed (TRS) are varied during machining. Machining time, diameter at entry and diameter at exit are the response measures evaluated to examine the effect of chosen process parameters on them. A Taguchi L-9 orthogonal array design of experiment has been employed to frame the parametric combination of the process parameters, based on which experiments are conducted. Furthermore, analysis of variance (ANOVA) is carried out to find significant process parameters. Deviation of 14.16, 0.03 and 2.14% is observed between the experimental and predicted results at optimum condition of machining time (104 pF, 15 µm/s and 1000 rpm), diameter at entry (102 pF, 5 µm/s and 500 rpm) and diameter at exit (102 pF, 10 µm/s and 1500 rpm), respectively.
