Disc Cutter Ring Material and Its Processing Technology of TBM;

High performance ceramic composite tool materials;

Si_3N_4/TiC nanocomposite ceramic tool materials were fabricated by adding Si_3N_4 and TiC nanoparticles and with Al_2O_3 and Y_2O_3 as additives.

The author gave us the reasonable selection of tool materials、tool parameters and cutting parameters during turning of hardened steel in order to get the ideal cutting result.

This article, through understanding the high-speed cutting processing definition, discusses the high-speed cutting application characteristic, the high-speed cutting craft superior, the shortcoming in the mold processing, and it has analyzes the high-speed cutting ,cutting tool material choice and the application.

To strengthen the research and development of the cutting tool materials further and to select the cutting tool materials rationally, it is the important prerequisite of promoting high-speed cutting technology to use and develop extensively.

The important role and development of cutting tool materials in human history are introduced.

Choice of cutter materials when dealing with hard-to-be-cut material;

Some factors affecting the machinability of high manganese steel such as cutter materials,cutter geometrical parameters,work capacity,cutting force and cutter serviceability have also been discussed.

Self lubricating cutter materials are excellent in antifriction and wear resistance.

Application analysis of high-speed cutting tool materials;

Fuzzy cluster analysis of the physical and mechanical propterties of the cutting tool materials;

In recent years, the rapid development of cutting tool materials is obviously along with the development of coating technology and processing industry.
