New Approaches to Characterizing the Performance of Coated Cutting Tools

The paper deals with the properties of PVD and CVD coatings deposited on HSS or cemented carbide tools. Titanium -based ternary layers form the main topic. The substrate and coating properties related to straight and interrupted cut -ting of quenched and tempered steel are characterized. Differences in performance between coated tools are explained through a separate consideration of substrate and coating influences. In addition, the paper describes a new approach to analyzing the effects of the thermal properties of the “coated tool” composite on the type and progress of wear.
