| 520 | _aDuring the punching operation the work piece is subjected to residual stresses. A compressive layer of residual stresses is formed on the top side while a tensile residual stress layer is formed on the lower surface of the sheet, which create a bending moment on the sheet which lead to its unevenness. The unevenness can be stated as the non-flatness of the sheet metal on a flat surface | ||
