Cutting properties of the tool equipped with inserts made of mixed ceramics with a multifunctional coating

Influence of multifunctional coatings on cutting properties of the tool made of the mixed ceramics is investigated at cutting of hard-steel. Tool life tests are spent, as well as dependence on a flank wear land of inserts from cutting time at dry machining is investigated. Mathematical models of tool life dependence from cutting condition at turning are received.

Keywords: mixed ceramics, coating, cutting tool resistance, flank wear.
