Abstract: In this research work pure titanium was machined with WEDM process with zinc coated wire electrode having Ø0.25 mm. Experimentation was conducted as per Taguchi's L27 orthogonal array for investigating the influence of process parameters such as pulse on time (TON), pulse off time (TOFF), peak current (IP), wire feed (WF), wire tension (WT) and servo voltage (SV) on surface integrity of the titanium. Scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX) analysis was performed for selected WEDM machined samples of titanium. It was observed that changing the discharge energy level through systematic variation of WEDM process parameters results in significant variation in the surface characteristics (such as craters, cracks, debris, recast layer and spherical deposits), material migration from tool (wire) and inter-metallic compounds formed on surface of titanium after WEDM. A mechanistic model has also been developed for prediction of recast layer thickness using dimensional analysis.
