Nowadays, the functional integration of workpieces challenges existing forming processes. The combination of established forming processes – like sheet metal and bulk forming – offers the possibility to counter this issue. The application of bulk forming operations on sheet metal semi-finished products, also called sheet-bulk metal forming (SBMF), is an innovative approach. The potential of SBMF cannot be fully exploited, as there are no recommendations in terms of workpiece design and layout influence on the process result. Therefore, this paper focuses on the analysis of semi-finished products and component design parameters on resulting part and process properties in two extrusion processes in SBMF. The investigation is based on a combined numerical and experimental approach. It is shown that the investigated design parameters, in addition to the achievable dimensional accuracy, substantially influence the occurring tool loads as well as the required process forces.

如今，工件的功能集成对现有的成型工艺提出了挑战。既定的成型工艺（如钣金成型和批量成型）的组合提供了解决此问题的可能性。将散装成形操作应用于钣金半成品（也称为钣金成形（SBMF））是一种创新方法。SBMF的潜力无法得到充分利用，因为没有关于工件设计和布局对工艺结果的影响的建议。因此，本文着重分析了SBMF中两个挤压过程中的半成品和组件设计参数，以及由此产生的零件和过程特性。该调查基于数值和实验相结合的方法。结果表明，所研究的设计参数，
