With the development of science and technology, various machines have continuously put forward new technical requirements for the structural materials of components. Whether it is a brittle metal material or a plastic metal material. The material itself has an increase in the ratio of alloying elements, strength, and hardness. Some parts have to be processed after quenching and tempering or hardening due to process or structural requirements. In addition, some materials are super-hard, high-temperature alloys that are resistant to high temperatures or creeps, so processing is inevitably more difficult. One of the shortcuts to increase cutting productivity and reduce production costs is to use new tool materials or to reform the tool geometry.
