轨道成形作为一种增量体积成形工艺，可以应用于金属板，以创建定义的圆形板厚度特性。本文提出了一种工艺参数的调查，其对零件的几何形状和性能的影响。通过有限元模拟和实验研究，分析了各影响因素。成形力、滚转角和润滑剂是影响成形充填的主要因素。但是旋转的次数决定了厚度分布的不均匀性。通过与镦粗工艺的比较，显示了该工艺的潜力。(C)2012年CIRP。
Orbital forming as an incremental bulk forming process can be applied on sheet metal to create a defined circular sheet thickness characteristic. This paper presents an investigation of the process parameters with their effects on the part geometry and properties. With FE-simulation and experiments the influencing parameters have been analyzed. The forming force, tumbling angle and lubricant were identified as the main influencing factors on the form filling. But the number of rotations governs the inhomogeneity of the thickness distribution. The potential of the process is shown by a comparison to an upsetting process. (C) 2012 CIRP.
