Cutting heat and cutting temperature is another important physical phenomena in the cutting process of the imported bearing materials. Caused by cutting heat cutting temperature, so that the workpiece thermal deformation. Directly affect the machining accuracy and surface quality of the imported bearing materials. The cutting temperature and tool life. Therefore, the generation and variation of the cutting heat and cutting temperature, there is a very important practical significance.

Cutting heat produce imported bearing materials and outgoing, in the role of cutting tool, cutting the metal layer elastic deformation and plastic deformation, which is a source of cutting heat; Chip and rake face, friction and power consumption between the workpiece and the flank will also be converted to heat energy? This is another source of cutting heat. Cutting heat conduction by the chip, workpiece, tool as well as the surrounding media out. According to the principle of thermodynamic equilibrium, the heat generated and diffusing the heat equivalent.
