摘要

An extensive study has been undertaken to investigate the tool-wear mechanisms of CBN cutting tools in finish machining of the following hardened steels: X155CrMoV 12 cold work steel (AISI D2), X38CrMoV5 (AISI H11) hot work steel, 35NiCrMol6 hot work steel and 100Cr6 bearing steel (AISI 52100), treated at 54 HRC. A large variation in tool-wear rate has been observed in machining of these steels. The generated tool flank grooves have been correlated with the hard carbide density of the workpieces. A crater wear study has also been performed and, it is shown that the appearance of an adhered third body could induce a chemical wear in the tool.
