Abstract
Good corrosion resistance, high specific strength, superior high-temperature performance and good fatigue resistance makes titanium and its alloys excellent candidate for biomedical, automobile, marine and aerospace component manufacturers. However, higher machining cost due to excessive tool wear and low material removal rate restricts its share in current engineering market. High hardness and ability to retain it at extreme temperatures, strong chemical affinity, low modulus of elasticity and poor thermal conductivity are the main reasons for poor machinability of titanium alloys. In this paper, based on available literature, machining difficulties such as variable width and thickness of chips, thermal stresses, severe pressure on cutting tool, tool wear, springback effect and residual stress are reviewed and underlying mechanisms behind these difficulties are presented. At the end, potential research issues are highlighted.
