The problem is usually simplified, which means simplified relations for the calculations of theoretical surface roughness during copy milling with cylindrical ball-end cutters are introducedČ the calculation of parameter Rz, and the maximum height of the undulation profile.In this contribution an improved calculation, not only for parameter Rz , but also for parameter Ra, the arithmetical mean deviation of the profile, is presented. The paper presents new equations for the direct calculation of the arithmetical mean deviation of the transverse and longitudinal profiles during copy milling on a plane (face) surface and an oblique surface</dc:description><dc:description xml:lang="sl">Hrapavost povrsine, kot posledica frezanja s krogelnim frezalom, je v strokovni literaturi in univerzitetnih učbenikih le redko opisana. Problem je pogosto poenostavljen. Kar pomeni, da so uporabljena poenostavljena razmerja za teoretične izračune hrapavosti površine pri kopirnem frezanju s krogelnim frezalom: računski parameter Rz in največja višina valovitosti profila. V tem prispevku je predstavljen izpopolnjen izračun, ne samo parametra Rz, ampak tudi parametra Ra, aritmetičnega srednjega odstopanja profila. V prispevku so predstavljene nove enačbe za neposredni izračun aritmetičnega srednjega ostopanja prečnih in vzdolznih profilov pri kopirnem frezanju ravne površine in poševne površine</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-F92NHMHL"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-F92NHMHL" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-F92NHMHL/42d61558-8888-4c69-aafd-73f1206abcac/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-F92NHMHL/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-F92NHMHL" /></ore:Aggregation></rdf:RDF>
