Abstract: The machining of M42 tool steel is discussed in this paper. Traditionally, these materials have been machined using uncoated cutting tools with limited success. New developments in titanium-based coatings such as cation-substituted Ti_l-x-y-zAl_xCry_yY₂N alloys, with y = 0.03 and z = 0.02, have been shown to offer enhanced high-temperature oxidation resistance compared to presently used TiN and Ti_l-xAl_xN films that are deposited to cutting tool surfaces. Machining experiments indicated that cutting tool life is improved significantly using yttrium-doped titanium based coatings, when machining M42 tool steels.
