Abstract

The hard turning of AISI 4340 is taken as an example. First, thermo-mechanical coupled cutting model is set up with AbaqusExplicit software. Then, different friction coefficient for chip formation is studied for the reason of crack and heat softening. Additionally, another increased strain energy release rate is studied with different friction coefficient. Finally, the result shows that the friction coefficient plays an important role in the formation of saw-tooth chip, especially when the strain energy release rate increases.
