Diffusion Wear of PCBN Tool when Cutting Materials Difficult-to-Cut Based on Thermodynamics

Applied Mechanics and Materials, 2014
Cutting temperature always highly reaches over to 1000°C when high speed machining with PCBN tools. Diffusion of tool material element may have important influence on tool wear at such high temperature, the diffusion wear and oxidation wear have become the major wear mechanism.

Turning of hardened 100Cr6 bearing steel with ceramic and PCBN cutting tools

Journal of Materials Processing Technology, 2003
Abstract This work deals with the machinability of hardened 100Cr6 bearing steel (62–64 HRC) when continuous dry turning using mixed alumina, whisker reinforced alumina and polycrystalline cubic boron nitride (PCBN) inserts. A full factorial experimental design was employed and the cutting range tested was as follows: cutting speed varying from 70 to

Optimizing PCBN cutting tool performance in hard turning

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2008
Surface finish, in addition to tool wear, is an important aspect of PCBN tool performance in hard turning. A set of experiments that focused on the effects of corner radius, chamfer angle/width, and edge radius in addition to severity of interruption and speed/feed at constant depth of cut were performed.

The flow stress of PcBN cutting tool materials at high temperatures

International Journal of Refractory Metals and Hard Materials, 2001
Abstract The onset of plastic deformation has serious implications when predicting the useable life of a cutting tool material. Through simulation of the tool/workpiece interface it is possible to determine the combination of mean pressure and temperature that would produce plastic deformation in these materials.

Wear Rate of PcBN Cutting Tools Equipped with Nanolayered Protective Coatings

Journal of Superhard Materials, 2020
We consider the effect of protective PVD coatings of various chemical compositions on the wear rate of cutting tools equipped with polycrystalline superhard materials (PSHM) based on cubic boron nitride (PcBN). A coating of the nanolayered structure was applied to cutting inserts made of superhard composites of the BH group by a vacuum-arc method using
