Hard turning of GCr15 steel with chamfered PCBN tools

International Journal of Manufacturing Research, 2013
This work investigates the cutting performance of chamfered PCBN tools in hard turning of GCr15 bearing steel. Experimental study was performed on a NC lathe. Cutting forces were measured by using a dynamometer. Cutting temperature was measured by using an infrared thermal imager. The variation of cutting forces and cutting temperature with the chamfer

Hard Turning with PCBN Tooling

1999
Material removal, at economic rates, from hardened workpieces has always presented a challenge and, until quite recently, abrasive machining processes were the only option for hard-facings. However, cutting tools based on polycrystalline cubic boron nitride (PCBN) have opened up the possibility of turning and milling as attractive alternatives for ...

Wear mechanisms of PVD-coated PCBN cutting tools

Wear, 2013
Abstract The wear characteristics of PVD coated (TiN, TiSiN, TiAlN, and AlCrN) polycrystalline cubic boron nitride (PCBN) cutting tools were compared to those of uncoated PCBN during single point turning of case hardened steel 16MnCr5. Post-cutting observations of the worn inserts were performed using high resolution field emission gun scanning ...

Diffusion and oxidation wear of PCBN tool based on thermodynamics

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2010
The rules of diffusion wear and oxidation wear for PCBN cutting tools were analyzed based on thermodynamics theory. Dissolution concentrations in typical normal workpice materials of PCBN tool material at different temperature were then calculated. Diffusion reaction rules in high temperature were developed and analyzed using the Gibbs free energy ...

On machining of hardened AISI D2 steel with PCBN tools

Journal of Materials Processing Technology, 2006
Abstract This paper describes an experimental investigation on machining of a difficult-to-cut material, AISI D2 steel of hardness 62 HRC with PCBN tools. It was found that the most feasible feeds and speeds fall in the ranges 0.08–0.20 mm/rev and 70–120 m/min, respectively and that most of the tested PCBN tools reached the end of life mainly due 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.
