Development of Advanced Surface Engineering Technologies for the Benefit of Multipoint Cutting Tools

Abstract

The benefits of applying advanced coatings on both single point and multipoint cutting tools such as improvement of productivity, tool life, machined surface quality etc. have been realised environments. This is because the end performance of coated cutting tools is not only dependant on the coating itself but also on the substrate material, geometry, surface finish and cutting edge conditions prior to coating deposition. The paper presents case studies with examples of successes and failures of advanced coatings on different multipoint cutting tools (e.g., milling cutters, bandsaws, circular saws, holesaws etc.). The future strategy for developing successful coating technology for cutting tools should be directed towards adopting a systems approach to bridge the communication gap amongst the cutting tool manufactures, tool coaters and end users.

Prospects of application of modern wear-resistant coatings to improve the performance properties of combined cutting and forming tools for finishing of cylindrical gears

“…The key factor in the wear of tools of the considered design is not permissible, but dimensional wear along the back (involute) surface of the tooth, which, as can be seen from the graph, occurs much earlier. Note that the predicted dimensional wear of a tool with a protective coating should decrease by almost 1.5 times, which is a very positive factor that speaks for the applicability of coatings [9,10].…”
