Abstract
In turning process, tool life is closely related to the thermal load generated during cutting, as it contributes to different wear mechanisms. Regarding to this and considering the difficulties associated with the measurement of temperature at the tool tip, several researchers have been working in different methods for its prediction. In this context, a finite element model was developed and adjusted with experimental data in order to predict temperature gradient during turning of a stainless steel. The obtained results demonstrated that different convection coefficients should be set for different cutting conditions and that a fixed percentage of electric motor power measured during the process can be used as an input parameter in the numerical model to predict the thermal gradient in the cutting insert.
