Cutting Tool Temperature in Cylindrical Turning

Résumé

This paper is presenting a numerical model for tool temperature during cylindrical turning process. A Fourier series approximation is used as a pattern for cutting tool temperature and this model is loaded with constant and variable heat flux input as well as convective cooling conditions. The influence of the temperature dependent material properties is also taken into consideration. The influence of these conditions on the cutting tool maximum temperature position and level is analyzed as a factor for determination of the tool wear.
