Abstract
To spin a metal sheet around a chuck for forming a product, in a teaching phase involving force control, a product is formed on the chuck by rotating the chuck about the axis of rotation and by moving a forming roller one or several times alongside the chuck with a pre-determined pressure force thereby spinning the intermediate metal sheet. In the teaching phase, measuring data corresponding to the movement of the forming roller during spinning is fixed in a memory of a control unit, and in the production phase the forming roller is controlled with the aid of these measuring data. The control unit determines the position values of the forming roller in axial direction and in transverse direction relative to the chuck from the data fixed in the teaching phase, and the control unit controls the forming roller in the production phase at least during a part of the spinning movement by means of the position values determined in this manner for spinning the metal sheet into the desired product.
