Summary

A series of seven different cutting tools was used for short-duration cutting tests on 1045 steel at 300 m/min (1000 surface ft/min). With the exception of TiN-coated cemented carbide, all tools were structurally stable. A very high wear rate was obtained for SiAlON tools, due to the combination of chemical and mechanical effects. All other tools exhibited plastlc-deformatlon-type wear as the dominant mechanism. All of the tools exibiting plastic-deformation-type wear had very low wear rates. In alumina-based ceramic tools the wear resistance increased with addition of TiC and decreased somewhat with the addition of zirconia, corresponding to the hardness changes.
