One of the most important achievements in this sector is the fact that nowadays it is possible to produce fully dense metal parts. Generally, additive manufacturing technologies are able to produce very complex geometries but are time and cost consuming for manufacturing of massive components. Machining technology, on the other hand, has the opposite characteristics. Both technologies, additive and subtractive, have advantages and disadvantages depending on the amount of material that need to be added or subtracted. The combination of these two technologies (i.e. hybrid manufacturing) results in a process where advantages of both technologies can be expected (cost, material consumption, etc.). Thus a novelty, the paper presents a development and analysis of software that analyzes the CAD model with geometry of the model and declares which part of model will be manufactured with machining and which will be produced by additive manufacturing. The software is evaluated on an industrial case from the field of injection mould inserts. Results show that such an automated algorithm decreases cost, better efficiency and nevertheless offer possibility to implement technology in industrial environment to improve manufacturing processes, i.e. in current case injection moulding process/technology"},{"@xml:lang":"sl","#text":"V članku je predstavljen razvit algoritem, ki je namenjen prepoznavi geometrije CAD izdelka, za izdelavo po postopku hibridne izdelave. Hibridna izdelava v našem primeru pomeni združevanje tehnologij odvzemanja materiala in dodajanja materiala po plasteh, gre za postopka odrezovanja in selektivnega laserskega pretaljevanja kovinskih prahov. Pri tem se izkoristi prednosti posamezne tehnologije in s tem eliminira slabosti. En del izdelka se izdela s postopkom odrezovanja, drugi del pa se doda na ta prvi del s postopkom selektivnega laserskega sintranja. Razvit je bil algoritem OMOS, ki prepozna geometrijo CAD modela predvidenega izdelka in na podlagi te geometrije določi, kateri del se bo izdeloval s katero tehnologijo. S tehnologijo dodajanja materiala po plasteh je možno narediti izdelke zelo kompleksnih oblik, vendar ta tehnologija spada med dražje. Med tem ko tehnologije odrezovanja ne dopuščajo izdelave izdelkov, ki imajo zelo kompleksne geometrijske oblike, saj takšne oblike preprečujejo dostop rezalnemu orodju do površine, katera mora biti obdelana. Je pa ta tehnologija bistveno cenejša od sodobne tehnologije dodajanja materiala. Zato je bila osnova za algoritem OMOS vzeta predpostavka, da se čim večji delež izdelka naredi s tehnologijo odrezovanja, kjer je to le mogoče potem pa se na ta del dogradi še preostali del izdelka s tehnologijo dodajanja materiala"}],"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-P98OILCG","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-P98OILCG"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-P98OILCG/5425a9bc-20c7-4052-ba4d-ccc2fdbf8bd9/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-P98OILCG/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-P98OILCG"}}}}
