【 摘 要 】

The finite element simulations of orthogonal cutting Ti6Al4V alloy were carried out based on Abaqus. The Johnson-Cook model was chosen as the constitutive model for the workpiece material, the parameters of the model for Ti6Al4V alloy were obtained through the SHPB (Split Hopkinson Pressure Bar) experiments. The cutting forces and thrust forces got from the simulations using different cutting parameters were observed and validated with the experimental results. A good agreement between the cutting and thrust forces got from the two methods indicated that the parameters of the constitutive model for the Ti6Al4V alloy, which were obtained from the SHPB experiments are correct and the finite element simulations of cutting processes in this work are reliable, so conclusions can be got as: the finite element simulations of metal cutting process can be widely used in practice to study more about the machining process and provide reliable dates for improving the manufacturing efficiency and the property of the machined workpiece in mechanical manufacturing industries.
