TÓM TẮT
This article presents predictions and comparisons of simulation results of the distribution of the effective stress in the cutting area, the distribution of heat in the cutting area and on the front surface of the cutting tool, the change in cutting force on the cutting tool in cutting two materials: Steel C45 and titanium alloy Ti-6Al-4V. The material of the cutting tool is WC-Co carbide. The orthogonal cutting model is created by the finite element method in the environment of Deform 3D V6.1. The thermal properties of materials in the model are functions of temperature. Based on the results obtained from the simulations, the maximum temperature on the chips and on the front surface of the cutting tool is determined and compared. Performing evaluations for the distribution of effective stress in the cutting area, the change in cutting force. The results of the article show that the working condition of the cutting tool in cutting titanium alloy Ti-6Al-4V is harder than the case of cutting Steel C45 in the same cutting mode. The elastic deformation of all elements of the technological system in cutting titanium alloy Ti-6Al-4V is greater than the case of cutting steel C45. These results show that it is necessary to choose a rational cutting mode, a rational cooling system, high rigidity of the technological system in cutting the titanium alloy Ti-6Al-4V in actual production conditions.
