Selection of Tool Steel for High-Speed Cutting (HSC) High-speed cutting (HSC) operates at very high cutting speeds and material removal rates, generating extreme strain rates and temperatures at the tool\u2013workpiece interface. Plastic deformation produces shear strains of 2\u20135 and strain rates up to 105 s\u22121 (locally reaching 107 s\u22121), with interface temperatures often exceeding 1000\u2103.
