An experimental approach to characterize the performance of PCD and PCBN tools in milling nano Al-8081-Zr/Mg/TiO2 metal matrix composites using multi-sensor data fusion

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science
To prevent the quality of the finished product from declining, precision manufacturing procedures need reliable cutting tool wear detection. Cutting tool material, workpiece attributes, cutting conditions and conditions, and excessive cutting forces ...

Wear and tool life of tungsten carbide, PCBN and PCD cutting tools

International Journal of Machine Tools and Manufacture, 2006
The wear mechanisms of cutting tools made of tungsten-carbide (WC), PCBN and PCD were investigated using the tool life and temperature results available in the literature. For tool/work combinations WC/steel and PCBN/hardened-steel, under practical conditions, tool wear was found to be greatly influenced by the temperature.

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

Wear model in turning of hardened steel with PCBN tool

International Journal of Refractory Metals and Hard Materials, 2014
Abstract In this study a mathematical–computational model of tool wear of PCBN (polycrystalline cubic boron nitride) was developed in turning of quenched and tempered AISI D6 steel (57 HRC) using experimental planning and statistic techniques. On the experimental trials many parameters are important such as: surface roughness, cutting force and tool ...

Cutting temperatures in hard turning chromium hardfacings with PCBN tooling

Journal of Materials Processing Technology, 2004
Abstract Hard turning of high chromium hardfacing materials is a new application field for PCBN tools. An investigation of the cutting temperature is essential in understanding the machining mechanism of the material, thus to improve the process efficiency.

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.

Machining Abrasion-Resistant Hard-Facings with Pcbn Tools

2002
Iron-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 ...

PCBN tool wear modes and mechanisms in finish hard turning

Robotics and Computer-Integrated Manufacturing, 2007
The use of polycrystalline cubic boron nitride (PCBN) cutting tools in hard turning applications is continuously growing with the number of commercially available grades increasing, allowing new application areas to be explored. In order to take full advantage of the benefits offered by PCBN it is necessary to understand the behaviour of the material ...

Wear Behavior of PCBN Tool in High Speed Turning TC4

Advanced Materials Research, 2012
PCBN tools were used for the turning of TC4. The cutting behavior and wear mechanisms were examined by means of the microscope, SEM and EDS analyses. The results have shown that ,the forms of the tool wear are mainly the rake face wear, flank wear, tip damage ,flaking and tipping; while the wear mechanism are mainly adhesion wear ,diffusion wear ...
