Machining of high performance materials such as titanium alloy keeps growing especially in the aerospace and medical industries. Due to the low thermal conductivity property of titanium material, there is thermal-related challenge which causes poor machinability and productivity. In this paper, influence of cryogenic cooling on tool wear and chip formation was investigated for turning titanium alloy at high speed cuttings. The results showed that tool wear resistance increases when using the developed cryogenic modular compared to oil-based coolant. In addition, a study on chip morphology showed different chip formations and thicker secondary deformation zone when machining under oil-based coolant condition compared to cryogenic condition.
