Improving Efficiency of End Mills by Deposition of Modifying Nano-Scale Multilayer Composite Coatings

Abstract

The study considers the challenge of improving the efficiency of end mills made of carbides through modification of physical and mechanical properties of tools by forming nanostructured multilayer composite coatings on its working surfaces with the use of filtered cathodic vacuum-arc deposition (FCVAD). The system and structure of three-component nanostructured multilayer composite modifying coatings for deposition on the working surfaces of the end mills are developed. The study presents the results of laboratory and industrial tests of end mills with coatings designed for conditions for rough and finish machining.
