Springback at free bending still represents one of the basic problems for this technology. In paper is evaluated springback effect of steel S235 rods with rectangular cross-section and thickness 5 and 10 mm. For springback effect measurement was used contact-less optical system ARAMIS 2M. Amount of springback was evaluated in dependence on the bending angle within the range from 5° up to 30°. Gained experimental results were compared with the theoretical calculations. |
