Abstract: In the deformation of geometrically similar components of a component family, in which the characteristic which differs is in particular thickness, there is according to conventional construction techniques of deformation tools a separate deformation tool necessary for each component. The inventive deformation tool system, including the following tool active parts stamp, blank holder and matrix, were in at least one work tool active part is shaped in a mask technique, enable the deformation of various components with this deformation tool system, in that for at least one tool active part at least two exchangeable masks of different characteristics are provided. Depending upon the component of a component family to be produced an optimal mask is selected from the pre-constituted supply of masks and used for deformation of the component in the deformation tool.
