Incremental Sheet Forming by Multiple Simultaneous Forming Zones (MPIF)

板料渐进成形（ISF）是一种用于生产几乎具有任何设计自由度的空心零件的成形工艺。与常见的金属板成形工艺（如深拉）相比，ISF的主要缺点是加工时间长。因此，零件的生产在小的成形区中进行。一个完整的零件的生产是渐进的。本研究项目的目的是通过在不同的成形区同时成形来缩短工艺时间。为此，IUL开发了一种工具原型，并获得了专利[Tek09]。模具原型由两个成型模具组成，可以同时移动。初步试验表明，节省加工时间的潜力很大。然而，为了通过增加工具数量来实现加工时间的潜力，基础研究是必不可少的。这种需求是由修改后的零件性能以及缺乏这种新工艺变体的工艺设计基础来证实的。这些原则将主要通过实验方法在该项目中开发，而另外，数值方法被辅助使用。

The incremental sheet forming (ISF) is a forming process for the production of hollow parts with nearly any design freedom. Compared with common sheet metal forming processes, such like deep drawing, a major drawback of the ISF is the long processing time. Hereby the production of parts takes place in small forming zones. The production of a complete part is gradual.The objective of this research project is to shorten the process time by simultaneous forming in separate forming zones. For this, a tool prototype has been developed by the IUL and was patented [Tek09]. The tool prototype consists of two forming tools, which can be moved simultaneously. The preliminary tests show a high potential for saving process time. To realize the potential of the process time by increasing the number of tools, however, fundamental research is indispensable. This need is substantiated by modified part properties as well as the lack of process design basics for this novel process variant. These principles are to be mainly developed by experimental methods in the project, whereas, in addition, numerical methods are supportingly used.
