On Ceramic Cutting Tools : In the Case of Machining Plain Carbon Steel

Abstract

This paper describes the experimental results about the relation between the physical properties and the life of ceramic tools, the cutting performance of trial products in comparison with a carbide tool of a steel cutting grade, and optimum tool geometry and cutting condition of ceramic tool, at machining 0.4% carbon steel. The results are as follows : (1) The cutting performance of ceramics is affected by the physical properties of ceramics. (2) The type of failure of ceramic tool is essentially the same as that of carbide tool. (3) It is necessary to choose properly tool geometry and cutting condition of ceramic tool for the increase of tool life.
