Conventionally, functional components with a load-adapted shape are manufactured by less resourceefficient processes. A resource-efficient manufacturing by metal forming is currently not economically feasible due to challenges in geometrical accuracy and tool-life. The aim of the investigations of the subproject T04 is to expand the technology of incremental sheet-bulk metal forming by a thermal grading of the mechanical properties in the forming zone. This enables a homogenization of the thickness distribution of the functional elements. Furthermore, the locally reduced yield stress decreases the mechanical tool-load, which increases the tool-life. This provides the basis for an industrial use of this technology and, thus, a resource-efficient manufacturing of functional components.

传统上，具有负载适应形状的功能部件通过资源效率较低的工艺制造。由于几何精度和工具寿命方面的挑战，通过金属成形进行资源高效的制造目前在经济上不可行。子项目T04的研究目的是通过对成形区的机械性能进行热分级来扩展板料-大块金属渐进成形技术。这使得功能元件的厚度分布能够均匀化。此外，局部降低的屈服应力降低了机械工具载荷，这增加了工具寿命。这为该技术的工业应用提供了基础，从而为功能部件的资源高效制造提供了基础。
