This paper considers new avenues of improving the efficiency of machining hardened steels using damping devices and nanostructured multilayered composite coatings deposited on ceramic cutting tools with innovative arc-PVD processes with filtration of vapor-ion flow. A developed technology allows reducing peak stresses arising during cutting-in and providing improved reliability of ceramic tools. It is observed that the formation of modifying coatings on an edge ceramic tool in machining of hardened steels with HRC > 50 under the conditions of damping can reduce the coefficient of tool failure variation down to 0.3, and that improves the ability to predict failure of ceramic tools and allows recommending ceramic tools for the use in automated production.
