An approach to evaluate the effect of cutting force and temperature on the residual stress generation during milling

摘要

Nowadays, the generation mechanism of the machined residual stress is still an uncompleted explored scientific problems, the major focus of the recent research is on the qualitative analysis on the formation resources (cutting force and temperature). In this article, a new model is built to quantitatively analyze the influence of the cutting force and temperature on the residual stress generation. Experiments and simulations are conducted to compare the cutting forces, temperature, and residual stress. Then, the specific correlation coefficients between the cutting force and temperature on the residual stress formation are calculated by the proposed model. According to the results, it can be concluded that the cutting force plays a leading role when compared with the influence of temperature on the generated machined residual stress. Moreover, the tangential residual stress is mainly induced by the tangential force and temperature. The radial residual stress is mainly determined by the radial force, and the effect of the temperature on the radial direction is less than the tangential direction. The proposed approach can better help to understand the residual stress generation and provide more evidence to control the distribution of machined residual stress.
