Abstract	The present study is undertaken to investigate the effect of hydrogen on the cutting performance of Ti-6Al-4V alloy by FEM. Mechanical behaviors of hydrogenated Ti-6Al-4V alloy are studied at elevated temperatures and high strain rates with split Hopkinson pressure bar. The Johnson–Cook model was developed combined with quasi-static experimental data. A numerical model is developed to simulate the cutting process. The results of the experiments and simulations agreed well. The results demonstrate that the presence of hydrogen has a significant effect on the cutting forces and temperature, and the cutting forces and temperature increase first and then decreased gradually with the increasing of hydrogen contents. The simulation results show that titanium alloys with 0.3% hydrogen have better machinability at high cutting speed.
