Calculation of bending correction factor K

U teorijskom dijelu završnog rada nabrojani su i opisani postupci oblikovanja deformiranjem prema tipu sirovca. Postupci se dijele na volumensko oblikovanje i oblikovanje lima. U tom dijelu govori se o savijanju te su nabrojane vrste savijanja, alati i strojevi za savijanje i opisane deformacije kod savijanja. U eksperimentalnom dijelu rada prikazan je izračun korekcijskog faktora pomaka neutralne linije. Izračun je prikazan na savijenome uzorku debljine „s“ pod određenim kutom savijanja „α“ te radijusom savijanja „Ri“. U nekoliko koraka kroz mjerenje i kontrolu uzorka, te izračunom dolazi se do korekcijskog faktora pomaka neutralne linije. Dobiveni rezultati faktora „K“ iz eksperimenta uspoređeni su pomoću programa PTC Creo Paramatric sa standardnim faktorom „K“.The final paper's theoretical section lists and describes the various deformation-based shaping techniques for each type of raw material. The procedures are divided into volume forming and sheet forming. In the experimental section, bending is covered along with its various types, tools, and equipment, as well as deformations that occur during bending. Within that part, the neutral line shift correction factor computation is also shown. On a bent sample of thickness "s" under a specific bending angle "" and bending radius "Ri," the computation is displayed. The correction factor for the displacement of the neutral line is calculated in various steps, through measurement and control of the sample as well as calculation. Next the PTC Creo Paramatric programme was used to compare the experimentally acquired "K" factor results to the standard "K" factor
