Numerical and experimental investigations of rotational swing folding

该项目的目的是生产旋转对称的零部件，而不会产生毛刺，并在小批量中减少最小的板材厚度。这一要求将通过采用新的渐进成形工艺旋转摆动折叠来实现。对于这种新的工艺技术，有必要确定工艺极限（起皱和板料减薄）。在所要求的项目中，必须获得关于轧制和板材厚度演变的基本理解。因此，将采用数值模拟和实验方法。通过应用所获得的知识，旋转对称部件将以高质量生产，没有皱纹和最小的板材变薄。

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.
