Abstract
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.

Title:Parametrization of band saw teeth geometry for cutting wood
Abstract:
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.

Keywords:carpentry, band saw, tooth geometry, parametrization, grinding machines, two-axis control
