Numerical and experimental investigations of rotational swing folding

该项目的目标是在小批量生产旋转对称部件而不起皱，并最大限度地减少板材厚度。这一要求将通过使用新的增量成形工艺旋转摆动折叠来实现。对于这种新的加工技术，有必要确定工艺极限(起皱和薄板减薄)。在被要求的项目中，必须对起皱和板材厚度的演变有一个基本的了解。因此，本文将采用数值模拟和实验相结合的方法。通过应用所获得的知识，将制造出高质量的旋转对称零件，并且没有起皱和最小的薄板减薄。

The aim of the project is to produce rotationally symmetric components without wrinkling and minimal sheet thickness reduction in small-sized lots. This requirement will be realized by using the new incremental forming process rotational swing folding. It is necessary to determine process limits (wrinkling and sheet thinning) for this kind of new process technology. Within the requestet project, a fundamental understanding about the evolution of wrinkling and sheet thickness has to be gained. Therefore numerical simulation and experimental methods will be used. By applying the gained knowledge, rotationally symmetric components will be produced with high quality and without wrinkles and minimal sheet thinning.
