Abstract

  • Incremental sheet metal forming offers the possibility of producing formed parts in small batches efficiently and in a resource-saving manner. However, in order to exploit this potential, a high level of process understanding and process-relevant material data are required. Based on experimental and simulation-based examinations, the forming limit curve (FLC) and fracture forming limit line (FFL) are determined to predict the material failure of critical geometry elements of the formed part (e.g., wall angle > 65°) by means of FEM and to avoid it via process adaptation. These critical geometry elements are experimentally validated via optical geometry measurements (GOM Atos).
