Orthogonal and steady state cutting mechanism can simulate with thermo elastic plastic FEM with Iterative Convergence Method(ICM). Using this method we can know cutting forces, cutting temperature, shear angle, stress and temperature distribution on tool face, etc. In this simulation, a flow stress characteristic model that depends on strain, strain rate, temperature and history of them was considerd to simulate cutting mechanism accurately.

Influence of rake angle

The influence of the first rake angle.
Tools are flat rake face tools.
These figures show the temperature distribution calculated.

Influence of cutting condition

The influence of the cutting conditions ( undeformed chip thickness ).
Tools are grooved rake face tools.
These figures show the temperature distribution calculated.
