Wear model in turning of hardened steel with PCBN tool ...

Campos et al. have studied the wear mechanisms when turning hardened steel (19MnCr5G/AISI 5115) with PCBN tools and found predominance of abrasion on both flank and rake faces of the tools. Abrasion on the surface of such a hard tool is most probably to be generated by the hard particles of CBN plucked out by attrition wear from the tool.
