Abstract

The extensive applications of Ti6Al4V α+β phase titanium alloys in aviation and biomedical industries are common nowadays, mainly due to their poised superior advantages such as good strength-to-weight ratio, excellent fatigue resistance and high corrosion resistance. However, titanium alloys are regarded as difficult to cut materials because of their low thermal conductivity at elevated temperature which causes unfavourable to machine process. Localized heat at the tool tip during machining speeds up tool wear, high temperature is intensified at the tool work-piece interface which deteriorates the tool life ultimately, leads to poor surface finish and surface integrity. In this paper, ultrasonic assisted diamond turning (UADT) of titanium alloys were conducted, which is newly applied in ultra precision machining area. The surface roughness of Ti6Al4V alloys after UADT by ultra precision machining was found to be improved. Important machining parameters such as cutting speed, feed rate and depth of cut were adjusted as variables during experiments. The influences of these machining parameters on the surface integrity of Ti6Al4V were examined and they were expected to contribute to the optimization process of UADT machining parameters in ultra precision machining.
