尽管增量成形与传统成形工艺相比具有明显的优势，例如交货时间短、安装成本低，但该工艺仍然存在一些缺点。除了可获得的精度之外，该工艺的主要挑战之一是工艺限制。由于可以形成的最大壁角对于特定的板材材料和厚度限制在给定的角度，因此许多工件几何形状无法制造。对于这种方法已经提出了不同的解决方案，本文进一步研究了其中的一种解决方案，即单点增量成形的多步骤方法。进行了实验并与模拟进行了比较，以更好地了解改进的工艺性能背后的现象。
Although Incremental Forming offers distinct advantages over traditional forming processes, such as short lead times and low setup costs, the process still has some drawbacks. Besides the obtainable accuracy, one of the main challenges of the process are the process limits. Many workpiece geometries cannot be manufactured due to the fact that the maximum wall angle that can be formed is limited for a certain sheet material and thickness to a given angle. Different solutions to this approach have been proposed and this paper further investigates one of those solutions, the multi step approach for single point incremental forming. Experiments were performed and compared with simulations to better understand the phenomena underlying the improved process performance.
