Process-Specific Material Characterization: Theory and Practical Implementation
Presentation Abstract: In the production of formed sheet metal parts, the formability of semi-finished products plays a crucial role. However, batch fluctuations in material properties often lead to reduced formability, particularly in complex-shaped components, resulting in scrap and high rejection rates.
This presentation introduces a method for evaluating material batch workability based on the Erichsen cupping test. Unlike the conventional test, this approach adapts the test geometry to specific components. The entire force-displacement curve is recorded and analyzed using data-driven prediction models. The final analysis provides insights into the workability of tested material batches, improving production efficiency and reducing waste.
