【Abstract】 A global review of the flexibility of machining hardened steel with PCBN tools was promoted in this paper based on the physical and wear behavior of PCBN tools, the mechanism of saw\|tooth chip, the characteristic of cutting forces and recent cutting mechanism, the surface integrity etc. Emphasize on the wear behavior of PCBN tool, the white layer and residual stress, it also give a feasibility of machining hardened steel with PCBN tool.更多还原
