Abstract

Pri 3D modeliranju izdelkov, krivljenih iz pločevine, je zelo pomembno poznati točne vrednosti k-faktorjev, da se lahko dosega ozka tolerančna območja pri izdelavi. Tekom diplomske naloge so bili narejeni vzorci iz različnih materialov ter debelin pločevine, ki se jih je krivilo z določenimi parametri. S pomočjo reverzibilne metode za izračun k-faktorjev smo le-te izračunali in jih zapisali v tabelo, ki se sedaj lahko uporablja v podjetju. Zaradi ostalih parametrov krivljenja, uporabljenih glede na potrebe podjetja, je tabela pridobljenih k-faktorjev prilagojena podjetju, v katerem so se izdelki krivili. S pomočjo pridobljene tabele smo izračunali vrednosti razvitih mer pločevine ter jih primerjali z že obstoječimi podatki.

Secondary title:	Analysis of geometric parameters for creation of sheet metal based CAD models
Secondary abstract:	While 3D modeling sheet metal bending products, it is very important to know precise values of k-factor, so that narrow tolerances can be achieved during manufacture. For this paper to be written, samples were made from different materials and thickness of sheet metal. They were then bent based on specific parameters. Using the reverse method for calculating k-factor, we recorded them in a table that can now be used in industry. Due to other bending parameters used, based on company needs, the obtained k-factor table is adapted to the company in which the products were bent. Using the obtained table, we calculated the values of sheet metal blank lengths and compared them with already existing data.
