Abstract

The results of numerical experiments that reveal a correlation between the thermal load and microstresses in ceramics upon wearing the tools are considered. Particular features of the deformation processes in the ceramics surface layer at temperatures T = 1100–1200°C, at which cutters equipped with the inserts from nitride ceramics pass over to an unstable operation regime, have been defined. Based on the established regularities, a series of the innovative ceramic tools is produced.
