Tool wear and machining performance of cBN–TiN coated ...

PCBN is the dominant tool material for hard turning applications due to its high hardness, high wear resistance, and high thermal stability. However, the inflexibility of fabricating PCBN inserts with complex tool geometries and the prohibitive cost of PCBN inserts are some of the concerns in furthering the implementation of CBN based materials for hard turning.

Effect on cutting force in turning hardened tool steels ...

Cubic boron nitride (CBN) or polycrystalline (PCBN) inserts are widely used as cutting tool material in such high-speed machining of hardened tool steels—due to high hardness, high abrasive wear resistance, and chemical stability at high temperature. Cutting forces and feed forces were determined in the numerical simulations.
