Two approaches to the modelling of chip formation: rheological models and finite element analysis

摘要

Metal cutting is a complex process in which several mechanisms are at work simultaneously. The mathematical modelling allows carrying out research into the optimization of machining conditions. Usually, the study of cutting process is very complicated, because the material removal process is conducted in an extremely adverse environment with high temperature and pressure in the zone of cutting. Therefore, the main goal of these studies is to establish a theory that will predict chip formation dynamics, cutting forces, temperature, tool wear, which allows to solve practical problems. This work examines the simulation of chip formation during the process of cutting. The aim of the present research is to compare models based on rheological properties of metals with 2D Finite Element Models of chip formation process.
