[0002] The cutting tool known as the "teeth" of the machine tool is a tool for cutting metal, and its cutting part is a geometric body determined by geometric parameters. Since the cutting part of the tool directly participates in the cutting process, the geometric parameters of the tool are related to cutting force, cutting temperature and tool life. It is closely related, and it also affects the shape and quality of the processed workpiece surface. During cutting, the geometric parameters of the tool are extremely sensitive to the material properties. When facing different materials, it is difficult for a general-purpose tool with fixed geometric parameters to exert excellent performance. Therefore, choosing a tool with reasonable geometric parameters according to the characteristics of the material is the premise of ensuring excellent cutting performance. Although the test method can obtain cutting data close to the real one, it wastes a lot of time and the cost is quite high. The metal cutting finite element simulation technology is characterized by its low The advantages of cost, intuition and convenience are widely used in the field of metal cutting technology research, but when the materials are different and the geometric parameters of the tool are different, it is necessary to manually modify the parameters and repeat the modeling, and the degree of automation is low.
