Izdelava kontrabasa s CNC tehnologijo Manufacturing a double bass using CNC technology V diplomskem delu smo obravnavali izdelavo pokrova kontrabasa z uporabo 3D-skeniranja, CAD/CAM-programske opreme in CNC-tehnologije. Namen dela je bil izdelati digitalni model obstoječega pokrova kontrabasa ter pripraviti postopek njegove CNC-obdelave. Geometrijo instrumenta smo zajeli s 3D-skeniranjem iz več položajev, pridobljene preseke pa obdelali in iz njih v programu SolidWorks izdelali končni 3D-model pokrova. Pri modeliranju smo določili tudi spreminjajočo se debelino pokrova ter izdelali negativ, namenjen njegovemu vpetju med obdelavo spodnje strani. V programu Fusion 360 smo pripravili CAM-obdelavo, določili obdelovalne strategije in orodja ter izvedli simulacije posameznih operacij. Skupni simulirani čas CNC-obdelave negativa ter zgornje in spodnje strani pokrova je znašal približno 4 ure in 17 minut. Ugotovili smo, da izbrani postopek omogoča izdelavo zahtevne geometrije pokrova z dobro natančnostjo in ponovljivostjo ter zmanjšuje obseg ročnega oblikovanja. This thesis presents the manufacturing of a double bass top plate using 3D scanning, CAD/CAM software, and CNC technology. The aim was to create a digital model of an existing double bass top plate and prepare the process for its CNC machining. The geometry of the instrument was captured by 3D scanning from multiple positions, and the obtained cross-sections were processed in SolidWorks to create the final 3D model of the top plate. During the modelling process, the varying thickness of the top plate was defined and a negative mould was created for clamping the workpiece during machining of the underside. CAM operations were prepared in Fusion 360, where machining strategies and tools were defined and individual operations were simulated. The total simulated CNC machining time for the negative mould and both sides of the top plate was approximately four hours and 17 minutes. The results show that the selected process enables the production of complex top plate geometry with good accuracy and repeatability while reducing the amount of manual shaping required. pokrov kontrabasa 3D skeniranje SolidWorks Fusion 360 CNC-obdelava double bass top plate 3D scanning SolidWorks Fusion 360 CNC machining true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-13 07:16:05 2026-09-13 07:16:12 2026-09-13 07:16:12 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 1970-01-01 289001 61370.pdf 61370.pdf 1 34cd17bf-af32-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=247380 Biotehniška fakulteta 0 0 0
