FE Simulation of Diamond Turning with Different Friction Coefficients

摘要

In this work, a coupled thermo-mechanical plane-strain large deformation FE cutting model is developed to simulate diamond turning based on the updated Lagrangian formulation. As expected, the effects of friction coefficient on cutting forces, chip deformation, cutting temperature, flow stresses and shearing angle are investigated by FE simulations. The simulated results can be adopted as a reference to select the reasonable friction coefficient in diamond turning process.
