摘要:
The invention concerns a method for the creation of addendums (4) of tools for sheet metal formed parts (2). In the case of this method, fill surfaces (7) for the smoothing of irregular zones of a component edge (3) are generated. Initial directions (31) of sectional profiles (10) are determined in such a manner, that sectional profiles (10) at a distance from one another are arranged along a component (3, 8) with utilization of these initial directions (31) and that an addendum (4) is creatable by the connection of these sectional profiles (10).

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).

摘要:
The invention relates to a method for determining a geometrical object for modeling the geometry of a metal sheet forming stage (1) in a CAD system. According to said method, an operator is defined which links a first geometrical model with a second geometrical model. The link is associated with a method for physically modeling a treating process which transfers a forming stage (1) from a corresponding first state into a second state. When the first geometrical model is modified, the second geometrical model is automatically updated in accordance with the physical modeling concept. The physical modeling concept for forming stages is thereby integrated into the static geometrical model environment of a CAD system. The physical modeling method is a method for calculating a border line (3) of a forming stage in an initial state prior to a forming process from a geometry of the border line (3) in a resulting state after the forming process.
