چکیده
This paper studied the cutting properties of Ti-6Al-4V under cryogenic cooling to find a solution of improvement in tool load-carrying, thermal stress, tool life and finish quality. Firstly, this paper established a 3-D 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 reveal that the cryogenic cooling with liquid nitrogen can slightly increase the main cutting force but it canefficiently cool the cutting area, and the cooling will contribute to the deformation of chips and improving the finish quality.
