摘要：
The thermo-mechanical coupled cutting model is made with Abaqus/Explicit software focused on the case of hard turning of 40CrNi2M. In order to stop heat dissipation affecting the model, for the machined workpiece, a zero conductivity value of the machined material is adopted. With the cutting model, a parametric study is proposed of the fraction of frictional work converted to heat at the tool/workpiece interface. This study proves that serrated chip formation is the result of a softening phenomenon, and the heat fraction influences the tool damage directly.
