Modeling of the Machining Process by PCBN Tool with Self-adaptive Coating
2021The paper discusses the analytical calculation’s results of the effect of the self-adaptive coating on such parameters of the contact interaction at the cutting zone as average contact temperature and cutting force during machining of hardened steel with PCBN. The calculation procedure was realized in the form of an iteration algorithm.

Optimizing PCBN cutting tool performance in hard turning
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2008Surface 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.

Effects of Additives and CBN Grit Size on the Machinability of PCBN Tools
Materials Science Forum, 2006An investigation was reported on how to improve the machinability of PCBN tool for realizing the electric spark line cutting of PCBN tool. The machinability of the PCBN tool was evaluated in terms of its current conductivity. The influences of the additive compositions, additive concentrations and grit sizes of CBN on the current conductivity of PCBN ...

Machining Abrasion-Resistant Hard-Facings with Pcbn Tools
2002Iron-based hard-facings are a popular choice for abrasion resistant materials in industries as diverse as mining and food processing. Alloys forming chromium carbides dispersed in a relatively soft matrix are particularly effective because these carbides are usually present as relatively large micro-constituents, which present large surface areas to ...

Reducing Fracture Tendencies in PCBN FSW Tools
2009Abstract : The overall goal of this program is to increase the life of PCBN tools in friction-stir welding of high temperature metals. This will be achieved through the following objectives: (1) Understand the fundamental causes for limited lifetimes of PCBN tools during Friction-Stir Welding (FSW) of high temperature metals, including both wear and ...

To the Question of the Mechanism of the Effect of Coating on the Durability of Tools from PCBN
2020The paper discusses the results of the tool-life tests of PCBN cutting tool with PVD coating and the mechanism which could be accounted for declining of its wear rate. The results of research showed that in condition of finishing of hardened steel (52–54 HRC), PCBN with (TiAlSiY)N/CrN PVD coating demonstrated significantly lower wear rate parameter in ...
