Abstract

The widespread use of titanium alloys in particular, Ti-6Al4V in chemical, medical, marine, sport and aerospace industries is mainly due its strength-to-weight ratio that can be maintained at elevated temperatures with excellent corrosion and fracture resistance (Konig, 1979). On the other hand, Ti-6Al4V is considered notorious with respect to machinability due to its low thermal conductivity and strong chemical affinity with most tool materials which causes premature tool failure. In addition, the inhomogeneous deformation by catastrophic shear during machining tends to fluctuate the cutting force and with its low modulus of elasticity, thereby aggravating tool wear and chatter (Machado and Wallbank, 1990).
