TÓM TẮT
This article is aimed at studying, analyzing and comparing the level of vibration of the cutting head of the tool due to auto oscillation when turning various materials, which are C45 steel and Ti-6Al-4V alloy in the same cutting mode. By analyzing the physical model of the tool-workpiece system during turning, a mathematical model of the process of auto-oscillations of the tool-workpiece system, consisting of one degree of freedom, is constructed, taking into account the characteristics of the nonlinearity of the radial component of the cutting force. A tool-workpiece model based on the finite element method was created and modeling was performed in the Deform 3D V11 environment to determine the parameters used in the dynamic equations of the tool-workpiece system. The simulation of the mathematical model of auto- oscillations in the Matlab/Simulink environment has been performed. As a result of the article, analyzes and comparisons of the levels of auto-oscillations of the tool head and their influence on the quality of machined parts during turning of the above various materials in the same cutting mode are given.
