Abstract: Heat generation during metal cutting processes results in temperature rise in cutting tool and workpiece. The tool wear which can affect the tool life and surface quality of the workpiece is significantly depended on the cutting temperature. Modeling the heat generation during the cutting processes can be helpful for predicting the tool wear. This study introduces a novel model for the prediction of temperature in the cutting tool while the effect of cutting-edge radius is included in the model for the first time in the literature in terms of temperature prediction using thermo-mechanical approach with sticking-sliding friction model. The temperature distributions at the tool-chip and tool-workpiece boundaries were determined analytically, and the temperature distribution inside the tool was calculated using the Finite Difference Method. The study also examined the effects of cutting-edge geometry and cutting conditions on cutting temperature, which can be used in optimized selection of cutting parameters and tool geometry.
