In this study, surface roughness of material Ti-6Al-4V that is the micro-cylindrical workpieces is analyze involving the wire electrical discharge turning (WEDT). The effects of pulse intensity, voltage, wire tension, and rotational spindle speed are investigate and optimize using the response surface methodology (RSM). Based on the results, the surface of the machined workpieces deteriorates according to the violent energy density generate 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 at 5.9% compared to prediction.

Keywords: Micro-cylindrical machining, RSM, Ti-6Al-4V, micro-turning, WEDT
