Zasnova in izdelava dinamsko ustrezne velike CNC naprave : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoKošir, Tilen, inženir strojništvaZaključna naloga opisuje zasnovo in izdelavo velike dinamsko ustrezne CNC naprave. Zasnova je opravljena z izbiranjem konstrukcijskih rešitev preko primerjalnih matrik, s preliminarnim statičnim ... izračunom, ter z modalno analizo lastnih frekvenc naprave po metodi končnih elementov. Namen modalne analize je dvig najnižjih lastnih frekvenc konstrukcije že v razvojni fazi konstruiranja, s čimer se izognemo kasnejšim večjim amplitudam pomikov, ki vplivajo na kakovost obdelave izdelkov. Zaradi predvidene obdelave različnih materialov z različnimi rezalnimi orodji in obdelovalnimi parametri je vzbujevalna sila neznana, zato je bilo napravo z dinamskega vidika pred izdelavo mogoče optimirati le z dvigom najnižjih lastnih frekvenc. V delu so opisane potrebne poenostavitve naprave za ustrezno mreženje konstrukcije s končnimi elementi. Celotna naprava je bila analizirana postopoma po delih, ki so ekvivalentni konstrukcijskim podsestavom X, Y in Z osi. S pomembnimi konstrukcijskimi dodatki je bil dodelan le podsestav X osi, katerega najnižji lastni frekvenci sta bili povečani za faktor 2.1 in 3.1. Nazadnje je bila izvedena še modalna analiza celotne CNC naprave. V nadaljevanju je opisan postopek detajlnega konstruiranja CNC naprave, izvedba krmiljenja s koračnimi motorji, ter sama izdelava in montaža naprave.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [T.
