TRR 73: Manufacturing of Complex Functional Components with Variants by Using a New Sheet Metal Forming Process - Sheet-Bulk Metal Forming

发起跨区域的CRC 73是为了建立科学基础，以通过应用成形技术满足日益增长的高功能密度个性化技术系统市场。然而，对于薄壁功能部件，经典的薄板和大块成形工艺达到了极限。跨区域的CRC 73为考虑到生态和资源高效生产的成型技术及其组件范围的发展作出了重大贡献，通过将大块成型工艺应用于金属板材。该研究的目的是调查，以增加由金属板制成的部件的功能。在第一个资助期，基本问题得到了解决，这是由于板材和散装成形操作的结合。在第二个资助期，将第一个资助期的科学成果合并到工艺链中，同时增加了零件的复杂性。跨区域CRC 73在其第三个资助期的愿景是研究制造过程对工件性能特征的影响。在这种情况下，由制造过程引入的硬化和损伤对性能特性的影响是特别有趣的。再加上工件复杂性的不断增加，这将使设计工艺链以及所涉及的工艺的挑战升级。研究工作的重点将放在原有的和目前仍在应用的工艺、系统和材料三个领域，对板料-大块金属成形件的产品生命周期进行科学分析。在板材-大块金属成形领域的发展，将有助于确保和加强德国在日益激烈的国际竞争中的生产和技术地位，从而提高德国的经济实力。

The transregional CRC 73 was initiated to establish the scientific basics to meet the growing market for individualised technological systems of high functional density by the application of forming technologies. However, classic sheet and bulk forming processes reach their limits regarding thin-walled functional components. The transregional CRC 73 provides a major contribution to the devel-opment of forming technology and its range of components in consideration of ecological and re-source-efficient production by applying bulk forming processes to sheet metal. The research aims on the investigations to increase the functionality of components made from sheet metal. In the first funding period basic questions were addressed, that resulted from the combination of sheet and bulk forming operations. In the second funding period the scientific results from the first funding period were combined to process chains while the complexity of the parts was increased at the same time.The vision of the transregional CRC 73 for its third funding period is to research the influence of the manufacturing process on the performance characteristics of the workpieces. In this context the ef-fect of hardening and damage introduced by the manufacturing processes on the performance char-acteristics is of special interest. In combination with a continued increase in workpiece complexity this will escalate the challenges in designing the process chain as well as the involved processes. The focus of the research work in the original and still applied three areas of processes, systems and material will be the scientific analysis of the product life cycle of sheet-bulk metal formed workpieces. The development in the field of sheet-bulk metal forming will help to secure and strengthen the pro-duction and technology location Germany in an ever increasing international competition, which shall improve its economic power.
