Simulation of high-speed cutting process based on ABAQUS

摘要

Using the separation line technology,established a FE model of two-dimensional cutting process for AISI4340 steel and discussed some basic theory and pivotal questions associated with the simulation of cutting process including the Johnson-Cook material model,the contact model between tool and chip,criteria of chip separation and so on.In order to study the impact of tool rake angle on the chip morphology and the cutting forces,the high-speed cutting process for AISI 4340 steel was simulated based on ABAQUS software.Also,analyzed the influence of mesh azimuth on the chip morphology and its temperature distribution.
