Pulse and Work Revolution Parameters of Wire Electrical Discharge Turning on Ti-6Al-4V Alloy
The present study investigates the effect of process parameters on Wire Electrical Discharge Turning (WEDT) of Ti-6Al-4V alloy. WEDT is the promising technique, which is capable of producing precise cylindrical form component for all electrically conductive materials regardless of its hardness and toughness. This work discusses the effect of various machining parameters over the responses like Material Removal Rate (MRR) and surface roughness (Ra). Response Surface Methodology (RSM) method is adopted to conduct the experiment and ANOVA technique has been employed to identify the significant parameters. From the experimental results, the maximum MRR obtained is 1.3449 mm3/min and the minimum surface roughness value is 1.627 µm. Moreover, the ANOVA results indicated that the pulse off current has significant impact on MRR. In the case of Ra, Ton and Toff played predominant role on deciding the surface quality.
