目前，机械加工残余应力的产生机理仍是一个尚未完全探索的科学问题，目前的研究主要集中在对形成源(切削力和温度)的定性分析上。本文建立了一个新的模型，定量分析了切削力和温度对残余应力产生的影响。对切削力、温度和残余应力进行了实验和模拟比较。然后，利用该模型计算了切削力与温度对残余应力形成的具体相关系数。结果表明，与温度对产生的加工残余应力的影响相比，切削力起主导作用。切向残余应力主要由切向力和温度引起。径向残余应力主要由径向力决定，温度对径向的影响小于切向。该方法有助于更好地了解残余应力的产生，为控制加工残余应力的分布提供更多的依据。
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.
