Abstract (en)

[origin: EP2208552A1] The method involves clamping a sheet metal between a press-plate and a cutting plate (15), and guiding a cutting stamp (11) by a workpiece guiding device. The workpiece is cut by a cutting contour and cutting surfaces of the cutting stamp. An opposite acting counter holder (14) is guided in the cutting plate. A vertical relative motion and a rotative relative motion are taken in relation to the cutting plate by the cutting stamp during the cutting process. Extensions of cutting surfaces are laid one above the other. An independent claim is also included for a device for fine cutting a workpiece.
