Titanium and its alloys have found wide application in aerospace, biomedical and automotive industries owning to their good strength-to-weight ratio and high corrosion resistance. However, these alloys have very poor machinability, which attributed to their inherent high strength maintained at elevated temperature and low thermal conductivity leading to high cutting temperature. In the present work carbide cutting tools were used for the milling of Ti-6Al-4V. The cutting speeds selected in the experiment were 95, 100, 105 and 110 m/min. The axial and radial depth of cut was kept constant at 3 and 6 mm. This study explored the relationship between cutting speeds in milling of Ti-6A1-4V titanium alloy for tool wears and surface roughness of the workpieces. Surface roughness parameters Rc and R, were investigate using Mitutoyo Surf III surface tester. The results of experiments showed that tool wear and surface roughness of workpiece changed with cutting speeds.
