Aiming to effectively remove the cutting heat in machining process, the cutting tool with heat pipe cooling has been developed in recent years; however, there were few reports on the quantitative investigation of temperature at the tool-chip interface of this tool. In this work, a heat pipe cooling system was used to decrease the temperature of the cutter. The temperature at defined locations of the cutter in the dry turning of an AISI-1045 steel was obtained by the cutting test. The finite difference solution and an inverse procedure were used to determine the tool-chip interface temperature. It was found that with the increase of cutting speed, the tool-chip interface temperature and effective heat flux of the cutter will increase. The tool-chip interface temperature could be reduced by the heat pipe cooling. The temperature reduction was more obvious in higher cutting speed.
