Carbide type- K tools were used in this study. The results of the microhardness and surface-roughness analyses are presented. The microhardness measurements were conducted beneath the machined surface. The analyses of the surface produced are presented in a range of surface-roughness parameters. Relations between microhardness variations and surface roughness were obtained from the analysesPrispevek se ukvarja s kakovostjo in celovitostjo površine aluminijeve zlitini, nastale pri običajni in obdelavi z velikimi hitrostmi (VHO). V študiji so uporabljena orodja iz karbidne trdine skupine K. Predstavljeni so rezultati analize mikrotrdote in hrapavosti površine. Meritve mikrotrdote so izvedene tik pod obdelano površino. Analize obdelane površine so predstavljene v območju parametrov hrapavosti površine. Razmerja med spremembami mikrotrdote in hrapavostjo površine so dobljene iz analizTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
