Abstract

A study of bending parameter variations has been performed to improve the predictability of the springback in a free bending process. At first, the influence of bending parameters on the springback behavior and the flat length under quasi-static conditions has been investigated for different sheet materials. Therefore, a tool with an integrated optical measuring system has been used to determine the influences of bending angles, radii, component widths and orientations of the bending axis to the rolling direction on the sheet. Afterwards, the quasi-static parameter variation has been extended with different punch velocities to investigate its influence on the bending process, the springback and the flat length. Based on these results an extendable metamodel for correction factors was developed.
