The tool is an important part of the machine tool. It directly performs production and processing tasks and is an important tool for completing parts processing. From the selection of tool materials to the assembly of the tool to the use of the tool, it is closely related to the processing quality and accuracy. With the rapid development of the processing and manufacturing industry, various new materials and new technologies have emerged endlessly, and the materials and processes of tools are also constantly changing and updating. Facing increasing processing requirements, how to correctly use the tools to optimize the matching of the tools to the airport and better cooperate with the production and processing tasks is an important issue that is generally concerned in the field of modern machining.
