Finite element analysis of the orthogonal metal cutting under different rake angles

HUANG Dan LIU Chengwen GUO Yimu  
The orthogonal metal cutting process under plane strain conditions is analyzed with elastic plastic nonlinear finite element method. Cutting processes under different rake angles are simulated with general purpose finite element analysis program. The chip separation is based on a critical stress criterion simulated with a nodal release procedure. Simulation results show the effect of tool rake angle on the geometric shapes of the chip, the stress distribution, the strain distribution, the residual stress and the surface residual deformation of the machined workpiece. The relationship between the rake angle and the shearing angle is also analyzed. The findings of this paper validate some former experimental results and provide useful insights for understanding and improving the orthogonal metal cutting process.
