This paper studied the cutting properties of Ti-6Al-4V under cryogenic cooling to find a solution for improvement in tool load-carrying, thermal stress, tool life and finish quality. Firstly, this paper established a 3D cutting model of Ti-6Al-4V under cryogenic cooling with liquid nitrogen, and then set the parameters of material, friction model and cutting conditions. Based on this model, the results of chips’ shape, cutting forces and temperature distribution were obtained in the simulation with different cooling approaches. The results revealed that although the cryogenic cooling with liquid nitrogen can slightly increase the main cutting force, yet it can efficiently cool the cutting area, and the cooling will contribute to the deformation of chips thereby improving the finish quality.
