The effect of chamfer angle of polycrystalline cubic boron nitride cutting tool on the cutting forces and the tool stresses in finishing hard turning of AISI 52100 steel

Cutting experiments and finite element analysis (FEA) using ANSYS software have been carried out in this paper in order to investigate the effects of chamfer angle on the cutting forces and the cutting tool stresses, principal and von Mises stress, of polycrystalline cubic boron nitride (PCBN) cutting tools in finishing hard turning of AISI 52100 bearing steel. The obtained cutting force measurement tests and FEA results showed that the chamfer angle has a great influence on the cutting forces and tool stresses, especially in the passive force and von Mises stress distribution. From the present work, it can be drawn that critical chamfer angle is 20° in finishing hard turning of AISI 52100 bearing steel
