Temperatures of the carbide tip’s surface when turning stainless steel with a chamfered main cutting edge nose radius tool are investigated. The mounting of the carbide tip in the tool holder is ground to a nose radius as measured by a toolmaker microscope, and a new cutting temperature model developed from the variations in shear and friction plane areas occurring in tool nose situations are presented in this paper. The frictional forces and heat generated in the basic cutting tools are calculated using the measured cutting forces and the theoretical cutting analysis. The heat partition factor between the tip and chip is solved by the inverse heat transfer analysis, which utilizes the temperature on the P-type carbide tip’s surface measured by infrared as the input. The tip’s carbide surface temperature is determined by finite element analysis (FEA) and compared with temperatures obtained from experimental measurements. Good agreement demonstrates the accuracy of the proposed model.
