Description	Precision machining of hardened steels is a topic of high interest to substitute some abrasive operations. Machining of hardened steel differs from conventional machining because of the hardness of the workpiece materials and the cutting tool materials that are required. Hard materials are characterized by high hardness (> 45 HRC) and abrasiveness. The machining process requires the cutting tool of much higher hardness and also higher resistance of the abrasive wear. Advanced tool materials such as cubic boron nitride and ceramics cutting tools are considered to have the ability of cutting such steels. There are some advantages of hard cutting over the abrasive machining e.g. some characteristics of surface integrity. This paper deals with some aspects and the results of experimental research of the residual stresses in milling of hardened steels.

(en) Přesné obrábění kalených ocelí je dnes v popředí zájmu při náhradě brousicích operací. Obrábění kalené oceli se liší od konvenčního obrábění tvrdostí obráběného materiálu a použitím vhodných nástrojů. Kalené materiály jsou charakteristické vysokou tvrdostí (> 45 HRC) a brusným účinkem. Obráběcí proces vyžaduje nástroje o vysoké tvrdosti a také s vysokou odolností proti otěru. Moderní obráběcí materiály jako jsou kubický nitrid boritý a řezná keramika se ukazují jako možné pro obrábění kalených ocelí. Tvrdé obrábění může přinášet určité výhody ve srovnání s brousicím procesem, např. v charakteristikách integrity povrchu. Tento článek se zabývá některými aspekty a výsledky výzkumu zbytkových napětí při frézování kalené oceli. (cs)
