Abstract (en)
[origin: EP2662161A2] The method involves producing the active surface of the primary tool half (14). The active surface of the secondary tool half (13) is produced. The elastic deformability of one of tool half is considered during the generation of the active surface of the secondary tool half. The deformation function is applied to sheet metal holder (16) for determining an active surface of the sheet metal holder.
