http://sheetmetal.me/tooling-terminology/spring-back/ When calculating for springback, understand that the bend radius will spring open a small amount in the same manner as the angle does. This means that, unless you’re coining (and these days, chances are you aren’t), the formed, or forced, radius will be slightly smaller than the actual radius that’s … Meer weergeven Why exactly does springback occur? There are two reasons. The first has to do with displacement of molecules within the material, and the second has to do with stress and strain. As the material is bent, the inner … Meer weergeven Both punch and die angles are designed to account for springback and springforward. The die angle gets narrower as the width of the die opening widens. Basic … Meer weergeven While coining is one way of compensating for springback, it usually isn’t the best option and is rarely used anymore. Bottom bending can be a viable option, offering a higher degree of control over the bend angle, but … Meer weergeven Springback is a semipredictable factor when working with sheet metal.
