In the classical approach of tool-path generation for free-form surfaces, the tool movements are expressed as a linear interpolation. For this method of interpolation, the theoretical curves of the tool positions are approximated with a polygonal line. Consequently, the tool movements are discontinuous in tangency and curvature, which creates vibrations and consequently affects the finish of the surface. With the development of CNC interpolators that accept aB-Spline curve, it has become more advantageous to use them. In our work on the NURBS surfaces machined with a parallel-plane machining strategy on 3-axisCNC milling machines, we automate the generation of the tool path in terms of B-Spline curves by determining the minimum number of control points that give the best approximation to the different tool positions"},{"@xml:lang":"sl","#text":"Deli nepravilnih oblik, ki se uporabljajo pri načrtovanju in izdelavi kalupov, matric in aerodinamičnih oblik itn., so izdelani na 3-osnih ali 5-osnih frezalnih strojih.

S to metodo interpolacije so teoretične krivulje lege orodja aproksimirane z lomljenimi črtami. Gibi orodja so posledično prekinjeni v dotikališčih in v krivinah, kar povzroča vibracije in posledično vpliva na končno obdelano površino. Z razvojem RK interpolatorjev, ki sprejemajo zlepke, je še ugodneje, če jih tudi uporabljajo. Pri našem delu o NURBS površinah izdelanih s strategijo paralelnih ravnin na 3-osnih RK frezalnih strojih smo avtomatizirali določanje poti orodja z zlepki z določitvijo najmanjšega števila nadzornih točk, ki podajajo najboljšo aproksimacijo različnih položajev orodja"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-RNPN691I","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-RNPN691I"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-RNPN691I/300882b0-5ac1-4669-afbf-eff603014957/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-RNPN691I/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-RNPN691I"}}}}
