渐进式型材成形工艺是一种新型的沿型材中心线沿着变截面的管材和型材成形方法。创新的工艺设计实现了高工件复杂性和高工艺灵活性的结合。为此，开发了一种机器概念，并最终实现了原型。新机床由八个数控轴组成，可加工最大直径为80 mm的薄壁管和型材。机床的设计与控制系统相结合，形成了具有高度灵活性的成形技术，这是该工艺的优势。根据最终工件的形状，成形过程分为几个步骤进行，因此可以被视为渐进成形过程。此外，该工具概念支持运动学和形状封闭的成形过程。
The Incremental Profile Forming process (IPF) is a new method to manufacture tubes and profiles with variable cross-section design along the centre-line of the profile. The innovative process design enables the combination of high workpiece complexity and high process flexibility. For this reason, a machine concept was developed and finally a prototype realized. The new machine consists of eight numerically controlled axes, which allow the processing of thinwalled tubes and profiles with a maximum diameter of 80 mm. The design of the machine combined with the control system leads to a forming technology with a high degree of flexibility, which is an advantage of the process. Depending on the final workpiece shape the forming process proceeds in several steps and can therefore be considered as an incremental forming process. Furthermore, the tool concept supports both a kinematical and a form-closed forming process.
