Influence of Process Parameter Variations on Stamping-Bending Component Quality

Article Preview

Abstract:

Achieving high geometric accuracy is crucial in stamping and bending processes. Key influencing factors include the position of the blank within the coiled sheet, leveling, strip lubrication, contour cutting, and the sequence of bending. Currently, process design and parameter selection rely largely on the expertise of experienced engineers. To enable a data-driven approach, the exact effects and interactions of process parameters must be analyzed using combinations of settings, machine data, and measurements of all manufactured parts. This study presents variance, interaction, and quality analyses based on long-term production trials for busbars. Process parameters were combined according to a statistical experimental design. The results indicate positive effects from slight pre-bending of sheet strips, active leveling, material removal through contour cutting, and simultaneous bending operations.
