Abstract :

This paper investigates the Micro Electric Discharge Machining (Micro EDM) of titanium wrought alloy with brass as electrode. In this research work, the effects of four parameters, namely, current, capacitance, pulse on time and pulse off time were studied upon material removal rate (MRR), electrode wear rate (EWR), diametric overcut (DOC) and taper angle (T). The objective was to study the effect of input parameter individually on the final outcome. Response surface methodology was used to design the experiments and the performance characteristics in micro drilling operation were studied. The experimental result indicate that current is the most significant factor. At high values of discharge energy MRR and EWR were found high while shape accuracy distorted by interaction of other parameters among which pulse on time and capacitance plays important role.
