Upon examining the test pieces, it was observed that there is a positive correlation between the width of the piece and the required stamping force. This result is anticipated, considering that a larger amount of material necessitates deformation, leading to increased resistance in the stamping process. In contrast, maximum tool displacement yielded high values for specimens with extensive widths, whereas for those with moderate widths, it decreased significantly.
