本文的主要目的是优化新型非圆旋压工艺。为此，进行了数值过程模拟。优化方法（基于数值模拟）需要在此过程中对滚轮进给速率和滚轮操作角度进行有针对性的调整。经过优化过程，板材减薄量可减少近30%。其次，提出了旋转摆动折叠的新成形工艺并给出了第一个数值结果。事实证明，与使用圆柱形成形工具相比，使用凸形成形工具可以减少起皱。
The primary objective of this paper is the optimization of the new non-circular spinning process. To this end, a numerical process simulation was conducted. The optimization approach (based on the numerical simulation) entails the targeted adaption of the roller feed rate and of the operating angle of the roller during the process. As a result of the process of optimization, the sheet thinning could be reduced by nearly 30%. Secondly, the new forming process of rotational swing-folding is presented and the first numerical results are given. It is demonstrated that the use of a convex forming tool leads to reduced wrinkling, compared to the use of a cylindrical forming tool.
