Finite Element Study of Metal Cutting With Damage Effects
This paper studies the micro-cutting characteristics of Aluminum Alloy(A2024-T351)based on finite element method(FEM)simulations.The finite element general-purpose code ABAQUS is used for the numerical cutting modeling simulation purpose,and the Johnson-Cook damage law is applied to characterize the material and its ductile shear failure behavior.Numerical simulations of the metal cutting show that the cutting depth has effect on the temperature and stress distribution during the cutting process.It is observed that the damage properties of the material affect the chip formation and the parameters of the cutting tool also affect the cutting process.Comparison of the sequential cutting and one-step cutting was made and the results suggest that lower cutting depth may lead the reaction force and the stress induced in the process to be lower.
