Abstract: 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 includes the steps of: providing physical dimensions of an actual sheet metal part; a feature extractor computing, from these physical dimensions, a measured material flow metric representative of the geometry of the part after the forming operation; and a matching unit determining, from reference data and the measured material flow metric, a matching forming operation data set whose associated simulated material flow metric most closely matches the measured material flow metric.

Abstract: In a method, a data processing system and a computer program for the configuration of tools and/or processes for the manufacturing of formed metal parts, raw data (r) for the description of a geometry and of a condition of a formed metal part are calculated from a set of nominal simulation parameters (d,n) through the simulation of a metal forming process. From a set of nominal simulation parameters (d,n) in a simulation run a set of raw data is calculated and saved, the preceding step is repeated several times with a variation of the simulation parameters (d,n), and as a result of this further sets of raw data (r) are generated and saved, and a statistical analysis (10) of several or of all the saved sets of raw data (r) is carried throughout for the purpose of calculating statistical characteristic values (Cr) of the raw data (r).
