U radu je prikazan postupak savijanja lima prema tehnologiji rada. Savijanje lima spada u skupinu obrade metala deformacijom. Ovaj postupak karakterizira promjena oblika materijala bez odvajanja ili odnošenja čestica i bez promjene volumena. Postoji niz različitih postupka obrade metala deformacijom koji su neizostavni dio moderne proizvodnje osobito ih karakterizira visoka proizvodnost. Može se obrađivati velik broj materijala u hladnom stanju te se tim postupkom nastoje postići konačne dimenzije obrađivanog komada. Najčešće se obrađuju čelici i legure obojenih metala.This paper presents the bending process of the sheet according to the technology of work. Bending of the sheet falls into the metal processing group by deformation. This procedure characterizes the change in the shape of the material without changing the volume. There are number procedures of deformation metal processing that are an indispensable part of modern production, especially characterized by high productivity. A large number of materials can be processed in cold condition and by this procedure they are trying to achieve the final dimensions of the processed piece. Most commonly treated are steels and alloys of non-ferrous metals
