Abstract: The temperature measuring experiment, analysis of 3D temperature field and fuzzy comprehensive evaluation for temperature field are processed to obtain groove of indexable milling insert with better cutting performance to improve the temperature field and stress field of milling insert. Based on genetic algorithm and temperature field of milling insert and driven by fuzzy comprehensive evaluation of temperature field, the reconstruction algorithm of 3D complex groove of milling insert is presented as the heating density function being the target function. The new wave groove is obtained, and the groove reconstruction system is developed. The verification example shows that the new groove has better performance than before on temperature field. Other grooves could be reconstructed by this method.
