In a method for designing a formed sheet metal part, a method for displaying a visual representation (10) of the quality of the formed sheet metal part, the method comprising the steps of: simulating the deformation of the part by a forming process of the part, thereby computing thinning and thickening effects of the forming process on the part, for different values of a restraining force; displaying a visual representation of the part and of the thickening and thinning effects of different regions of the part; classifying the surface of the part as having several regions (11, 12, 13, 14, 15), each region being associated with a particular range of the thickening and thinning effects; computing and displaying on a display device (3) a diagram (21, 22, 23, 24, 25) displaying, as a function of the restraining force, the relative size of areas of these regions.

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).

A method for the characterization of a sheet metal forming product uses the correlation of material flow data to a priori calculated or measured data. It determines whether the product falls within the acceptable production limits in terms of quality, areas of potential defects and an approximation of the process parameters prevailing during its production. The characterization is performed in real-time during production, tool deployment or try-out. The method comprises the steps of providing physical dimensions (12) of an actual sheet metal part (10); a feature extractor (13) computing, from these physical dimensions, a measured material flow metric (14) representative of the geometry of the part (10) after the forming operation; a matching unit (15) determining, from reference data (33) and the measured material flow metric (14), a matching forming operation data set (16) whose associated simulated material flow metric (26) most closely matches the measured material flow metric (14).

In a method for designing a sheet-metal-forming process in which a sheet-metal part is formed, a visual representation of the sheet-metal part is computed and displayed. Visual labels are displayed, each label being visually linked to the representation of a feature of the part. The labels indicate one or more processing units of the sheet-metal-forming process that are assigned to the features. The labels can also indicate process operations to which these processing units are assigned.
