Problems solved by technology

[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.
