Hard turning in continuous and interrupted cut with PCBN and whisker-reinforced cutting tools

Journal of Materials Processing Technology, 2009
PCBN (polycrystalline cubic boron nitride) is the most widely used material for tools employed in hardened steel turning applications due to its high hardness, wear resistance and thermal stability. However, its high costs severely limit its use. Alumina-based ceramics reinforced with whiskers, an alternative and less expensive material for these tools,

The influence of the microstructure of hardened tool steel workpiece on the wear of PCBN cutting tools

International Journal of Machine Tools and Manufacture, 2003
Abstract Due to the recent developments of advanced cutting tool materials in the superbarasive family, such as cubic boron nitride (CBN) tools, the interest in cutting hardened steels has increased significantly. High flexibility and ability to manufacture complex workpiece geometry in one set up is the main advantage of hard turning compared to ...

Effect of chamfer angle on wear of PCBN cutting tool

International Journal of Machine Tools and Manufacture, 2003
In precision hard turning, a remaining problem is to minimise tool wear to maintain the accuracy of geometry and surface finish. Tool wear not only directly reduces the part geometry accuracy but also increases cutting forces drastically. The change in the cutting forces also causes instability in the tool motion, which results in more inaccuracy. PCBN

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.

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 ...

Optimisation of cutting conditions in hard turning using ceramic-coated and uncoated PCBN cutting tools

International Journal of Manufacturing Technology and Management, 2008
Traditionally, hardened steels have been finished by grinding, but improvements in machine tools and cutting materials allow machining of hardened steels. This research addresses the influence of cutting parameters on tool life and cost. Experimental tests were performed to calibrate the well-known Taylor life model, and validation tests with both ...
