<p>Processing steps are determined and optimized during the production of sheet metal forming parts, for example, using deep drawing/stretch forming processes. During the determination, using a computer-assisted design system, of process operations (PO1-PO6) for the description of forming processes on a forming part, the following steps are carried out: defining geometry models for the computerized description of a geometry of the forming part in a target state; defining several geometry operators (m1-m9, e1-e6), wherein one geometry operator (m1-m9, e1-e6) associates a geometry of an area of a first geometry model with a geometry of an area of a second geometry model, and the geometry operator (m1-m9, e1-e6) describes a transition from one of the two associated geometries to the other one; and defining several groups of respectively at least one geometry operator (m1-m9, e1-e6), wherein each one of the groups is respectively associated with a process operation (PO1-PO6).</p> |
