The difference of draw bead design in the part geometry has a significant effect on springback.
In this analysis, the accuracy of springback prediction is presented for three different models, that is, without draw beads, smooth draw beads, and locking draw beads.
Die manufacturing engineers tip the surface into die position, add draw beads and clamping surfaces, and merge the data to create a surface model of the stamped part.
