Abstract

In this paper, micro-electrical discharge machining of thin titanium alloy foil sheet (Ti–6Al–4V) is performed using 100-µm tungsten rod to study the output parameters such as recast layer thickness at entry and exit surfaces, material removal rate, linear wear rate and taper angle. The electrical input parameters considered in this research work are, namely, pulse on-time, current, pulse off-time and voltage. Further, SEM analysis reported is highly useful in calculating the output parameters originality for all input parameters combinations and additional value to the experimental observations. Grey relational analysis is employed to find the optimum machining parameter among the various combinations of electrical input parameters in micro-electrical discharge machining. The smaller hole is highly useful in fabrication of micro-products.
