The analysis of the latest reports on the subject shows that mathematical relationships used for determining surface irregularities after turning and milling are not complete or accurate enough and, therefore, need to be corrected. A new generalized mathematical model of roughness formation was developed for surfaces shaped with round-nose tools. The model provides us with a quantitative analysis of the effects of the tool representation, undeformed chip thickness, tool vibrations in relation to the workpiece, tool runout (for multicutter tools) and, indirectly, also tool wear. This model can be used to prepare separate models for most of the typical machining operations. Surface roughness is represented here by two parameters Ra and Rt. Simulations carried out for this model helped to develop nomograms which can be used for predicting and controlling the roughness Ra of surfaces sculptured by face milling</dc:description><dc:description xml:lang="sl">Proces oblikovanja površinske hrapavosti je kompleksen proces, ki je odvisen od številnih dejavnikov. Analiza najnovejših raziskav iz tega področja kaže, da matematične odvisnosti, uporabljene za ugotavljanje nepravilnosti površine po struženju in rezkanje, niso dovolj dodelane in natančne, zato jih je potrebno popraviti. Razvit je bil nov posplošeni matematični model oblikovanja hrapavosti pri obdelavi z zaokroženimi orodji. Model omogoča kvantitativno analizo vpliva izbire orodja, debeline nedeformiranih odrezkov in vibracij orodja na obdelovanec, odstopek krožnega teka orodja (pri večrezilnih orodjih) in, posredno, obrabo orodja. Model omogoča pripravo ločenih modelov za večino tipičnih operacij obdelave. Površinska hrapavost je predstavljena s parametroma Ra in Rt. Simulacije, opravljene za ta model, so omogočile razvoj nomogramov za napovedovanje in nadzor hrapavosti Ra površin, oblikovanih s čelnim rezkanjem</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-OQ4J0BME"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-OQ4J0BME" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-OQ4J0BME/4f2a7900-bb8b-4cd6-9a5e-93fb9b8eebb2/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-OQ4J0BME/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-OQ4J0BME" /></ore:Aggregation></rdf:RDF>
