PCBN Tool Wear Mechanism in Interrupted Hard Turning SAE8822 Hardened Steel

Abstract:

Article Preview

The wear behaviour in the precision interrupted hard part turning SAE8822 case hardened steel by BN250 PCBN cutting tool was studied. Experimental results showed that the main wear mechanism for the PCBN tool was the edge chipping by the fluctuation of cutting forces and cutting temperature. The oxidization and diffusion of the elements between workpiece and PCBN tool decrease the bonded strength between binder and cBN crystal, then lead to the damage of PCBN cutting tool.
