Sheet metal bending is one of the most common ways to get to the finished product or
semi-finished product. We tested bottoming and wipe bending to find out how these two
bendings are related. We had to make a prototype tool where subjects could be tested. We
tested six different materials, at three different bend angles and radius of bending and
determined the amount of springback that occurred after the bending process. We anelyzed
the influence of the material, angle and radius of bending on the springback and calculated
the loading factor. From the obtained results, we made a database that can be used for later
predictions of springback in material with similar mechanical properties.
