Abstract

Titanium alloys are widely used in aerospace industries because of their superior mechanical properties. However, titanium alloys are material that extremely difficult to machine because of their low thermal conductivity and high chemical reactivity. Recently, with increasing demands for precision machining of titanium alloy have brought the development of hard coating tools in terms of optimizing the acceptable tool life, and thus minimize tool cost. An investigation of cutting performance of uncoated and TiCN coated carbide tools when end milling of aerospace titanium alloy, Ti-6Al-4V was carried out. Machining tests were conducted at various cutting speed with constant feed and depth of cut. The performance for both cutting tools was evaluated with respect to tool wear, surface integrity of machined surface. Results show that the TiCN coated carbide tool was better than uncoated carbide tools in term of surface finish for all cutting speeds observed. Plastic deformation was found on the machined subsurface for both carbide tools
