20.500.12556/RUL-105113 Parametrizacija geometrije ozobij tračnih žag za razrez lesa Parametrization of band saw teeth geometry for cutting wood V magistrskem delu smo preučili tračne žage in že obstoječe profile ozobij tračnih rezil za lesarstvo, postopke njihovega ostrenja in parametrizacijo geometrije ozobja rezil. V delu obravnavamo pregled stanja tehnologije tračnih žag v žagarstvu in lesarstvu, izbiro in oblikovanje tračnih rezil, največkrat uporabljene tipske in unikatne profile ozobij rezil ter njihovo ostrenje. Preučili smo možnosti ostrenja ne enoosno in dvoosno krmiljenih brusilnih strojih. Parametrizirali smo geometrijo profilov ozobij tračnih rezil za namene hitre izdelave krmilnih programov za CNC-brusilni stroje. Rešitve smo preizkusili na tipskem NS profilu zob. Izdelali smo algoritem potreben za definicijo ustreznega gibanja brusilnih diskov pri ostrenju na CNC-strojih. In this master’s thesis we studied band saw machines and already existing tooth profiles of saw blades for carpentry, processes of sharpening of those and parametrisation of tooth geometry of the blades. In the thesis we discuss an overview of the state of band saws in sawmilling and carpentry, selection and formation of saw blades, most commonly used standard and unique tooth profiles and their sharpening. We studied sharpening options on single-axis and two-axis controlled grinding machines. We parametrised geometry of profiles of saw blades for the purpose of fast production of control programs for CNC-grinding machines. We tested the solutions on a standard NS profile of teeth. We designed an algorithm necessary for definition of suitable movement of grinding discs while sharpening on CNC-machines. lesarstvo tračno rezilo geometrija zob parametrizacija ostrenje brusilni stroj dvoosno krmiljenje carpentry band saw tooth geometry parametrization grinding machines two-axis control true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2018-10-26 16:02:39 2018-10-26 16:02:45 2023-10-18 09:32:41 0000-00-00 00:00:00 2018 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 209952 2864.pdf 2864.pdf 1 F5C10F6AEA52E85051F2F87CBFC0C1A6 a5798c59d6d4acf6d1afcdf770bd2d817f7a9829baa710304bbba5b463053aeb 1cb9d52f-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=115690 Fakulteta za strojništvo 0 0 0
