• This report deals in applications of ceramics in machining several kinds of work material and it is divided into three major parts : (1) Types of failure and wear process. In this chapter it will be discussed what kinds of failure will take place on the flank and the face of cutting tools and how it will increase. (2) Applicability of the tool life equation. With brittle tool materials such as carbide and ceramic tools, the relationship between the tool life T and the cutting speed V can not be expressed by a single line on the so-called V-T diagram. It has been clarified in this chapter that such a phenomenon is caused by the presence of the welded fragments on the cutting edge at low cutting speeds and heat shock at high cutting speeds. Thereupon the numerical values with the cutting conditions have been obtained theoretically and experimentally. (3) Applicability of ceramic tools in machining. Firstly reliability of several kinds of ceramic tools has been revealed experimentally. As a result, it has been verified that the smaller the transverse rupture strength and the higher the cutting speed, the variance of the tool life becomes the higher. Secondly the applicability of ceramic tools in machining steels has been discussed from the viewpoint of tool life. The results could reveal that the ceramic cutting tool would show a good cutting performance for high carbon steels and free machining steels in comparison with the carbide and TiC base cermet tools.
