An extensive study has been performed to investigate the tool-wear mechanisms of CBN cutting tools in finish turning of the following hardened steels: X155CrMoV12 (AISI D2) cold work steel, X38CrMoV5 (AISI H11) hot work steel, 35NiCrMo16 hot work steel and 100Cr6 bearing steel (AISI 52100), treated at 54HRC. A large variation in tool-wear rate has been observed in machining of these steels. The generated...
Compared with grinding, hard turning may induce a relatively deep compressive residual stress while still achieving an equivalent surface finish. Although it is generally agreed that deep compressive residual stresses are beneficial to component life in rolling contact, the interactions between the residual stress profile, applied load, and surface material are poorly understood at present. With the...
