The authors discuss how the smudges are created and show the results of computed tomography tests conducted for roller bearing rings with the above-mentioned defects. The ring reconstruction images are presented, and the defects are located and described with the use of reverse engineering. The defects identified are presented in radiographs. The topography tests confirmed the existence of subsurface defects that emerge on the surface in the form of smudges, once the grinding of an element starts</dc:description><dc:description xml:lang="sl">Članek predstavlja rezultate preskusov obročev kotalnih ležajev, pri katerih je bila med kontrolo na proizvodni liniji ugotovljena prisotnost nesprejemljivih površinskih napak v obliki brusilnih lis. Napake so bile ugotovljene po brušenju površine testnih predmetov. Zato je bila postavljena hipoteza, da imajo obroči kotalnih ležajev površinske diskontinuitete ali napake pod brušeno površino, spremembe v obliki lis pa se pojavijo zaradi odpiranja teh napak in kontaminacije v procesu površinske obdelave. Obroči, ki so bili zaradi ugotovljenih napak med kontrolo odstranjeni iz proizvodnega procesa, so bili pregledani s pomočjo računalniške tomografije (CT). Pri testih je bila uporabljena programska oprema Phoenix datos/x in VG studio max</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-WRV6XSP2"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-WRV6XSP2" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-WRV6XSP2/091432d6-5df0-46d5-b6ae-ffc2124a416d/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-WRV6XSP2/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-WRV6XSP2" /></ore:Aggregation></rdf:RDF>
