N2 - In forming technology, the principle of stress superposition is well known for a controlled influencing of the forming zone. The aim of stress superposition is to reach an additional plastification of the material, which can be used to compensate the springback effect, e.g. of bending angles or bending radii, to extend the forming limits of the material and to reduce the forming forces. The paper deals with two new forming process variants invented by the authors, which are based on the principle of stress superposition. The first is an air bending process using an additional roll for the incremental superposition of compressive stresses along the tensile zone of a bent sheet metal. The second is the new process of incremental tube forming, which is suitable for bending tubes two- and three-dimensionally to arbitrary contours. It is based on the combination of a spinning process with the free forming of tubes.
