In the case of cutting tests by ceramic tools, even when conditions are controlled with great care, the values obtained by repeated measurements will often show a considerable range of variation. So a number of tests are necessary to furnish reliable information. In this paper, the wear process of ceramic tools and the statistical characteristics of the cutting performance are discussed on the basis of many cutting tests under the same conditions. The results are as follows : (1) The relation-ship between the width of flank wear V_B and cutting time T is indicated quantitatively. That is [numerical formula] where V_<B0>, a, b are constants. (2) In this experiment, it has been revealed that the smaller the transverse rupture strength of ceramic tool materials and the higher cutting speed, the larger the variance of tool life becomes.
