Research on Cutting Force based on Thermal-mechanical Coupling Precision Modeling

Abstract

The accurate establishment of the constitutive model during the cutting simulation is very important. The improved finite element inverse method is used to establish an accurate material constitutive model, the optimal JC constitutive parameters are solved, and the Thermal-mechanical coupling model constructed with ABAQUS is obtained. An accurate cutting simulation model. The output is based on the cutting force in the case of Thermal-mechanical coupling, and it is compared with the experimental measurement values. The simulation values are basically consistent with the experimental values, which verifies the accuracy and feasibility of the model. It also provides reference and guidance for other accurate modeling of cutting simulation.
