Abstract In this study, a FEM-based tool wear approach with a focus on the geometry of the worn tool, especially the changes of flank wear land inclination angle, was developed. The relationship between the variables of the wear rate equation and the average nodal temperature on the flank wear land through integrating FE-simulations of the cutting process and Response Surface Methodology (RSM) was determined in order to define the temperature as a function of wear rate model parameters. Then, that data was used to calibrate the wear rate equation which was obtained by establishing the relationship between the Usui wear rate equation and the geometry of the worn tool, using a MATLAB program. This approach was validated by comparing the predicted flank wear rates and experimental measurements. The estimated flank wear shows some improvement compare to the model with a constant inclination angle.

基于后刀面磨损倾角变化的加工刀具磨损估计采用有限元法

摘要 在这项研究中，开发了一种基于有限元法的刀具磨损方法，重点关注磨损刀具的几何形状，尤其是后刀面磨损刃倾角的变化。通过整合切削过程的有限元模拟和响应面方法 (RSM)，确定磨损率方程的变量与后刀面磨损面上的平均节点温度之间的关系，以便将温度定义为磨损率的函数模型参数。然后，该数据用于校准磨损率方程，该方程是通过使用 MATLAB 程序建立臼井磨损率方程与磨损刀具几何形状之间的关系而获得的。通过比较预测的后刀面磨损率和实验测量值来验证该方法。
