Effect of Wire Electrical Discharge Turning Parameters on Surface Roughness of Titanium Alloy

Abstract

In this study, the surface roughness of material Ti-6Al-4V that is the micro-cylindrical workpiece is analyzed involving the wire electrical discharge turning (WEDT). The effects of pulse intensity, voltage, wire tension, and rotational spindle speed are investigated and optimized using the response surface methodology (RSM). Based on the results, the surface of the machined workpieces deteriorates according to the violent energy density generated by a high pulse intensity and voltage along with a low electrode wire tension and spindle speed. The optimal surface roughness obtains experimentally through the desirability approach is 4.0143 µm with a relative error of 5.9% compared to the prediction.
