Abstract
A method for producing dimensionally highly accurate sheet-metal components is provided. A blank is formed to a preformed part, wherein the preformed part in the cross section at least in regions has an excess developed length. The preformed part is calibrated in regions to a calibrated part while at least in regions using the excess developed length of the cross section of the preformed part, wherein the preformed edges of the preformed part during the calibrating are at least in regions disposed so as to be free of any form-fit. The calibrated part is trimmed at least in regions after the calibrating, in order for the sheet-metal component () to be produced. A device for producing dimensionally highly accurate sheet-metal components is moreover described.
