Patent ID: 8352057

Claim:
A method for feedback-based optimisation of a measurement data life cycle in joining processes during production, in particular in the manufacture of aircraft and in general mechanical engineering, comprising: 1) analysing and simulating production on the basis of assumptions, in particular on the basis of production data, in order to prepare an initial production strategy and/or inspection strategy, 2) preparing and/or adapting a production and/or inspection order, 3) checking the production and/or inspection order for consistency, 4) exporting and storing the production and/or inspection order, 5) aligning and/or joining a component made of at least two sub-assemblies in an assembly zone, 6) analysing and simulating production on the basis of actual measurement results and feedback of an optimised production and/or inspection strategy into the preparing and/or adapting a production and/or inspection order, and 7) at least one repetition of method steps 2) to 6), wherein in a method step 5a), the sub-assemblies are measured and metrological measured variables obtained therefrom are stored; wherein in a method step 5b), the metrological measured variables obtained in method step 5a) are evaluated, wherein in a method step 5c), a variance comparison is carried out between stored alignment parameters and measured variables, and the metrological measured variables evaluated in method step 5b) to determine a measurement deviation, wherein in a method step 5d), the measurement deviation determined in method step 5c) is compared with stored tolerances to assess the measurement deviation, wherein in a method step 5e), the assessment of the measurement deviation determined in method stop 5d) yields production data which is imported into a production history in a method step 5e) after a plausibility check has been carried out, wherein in a method step 0), a component design and/or a positioner design are prepared using at least one CAD system, the designs being stored as design specifications; and wherein the design specifications from method step 0), the production data determined in method step 1), the production and/or inspection orders resulting from method step 4), the metrological measured variables measured in method step 5a), the production data obtained from method step 5d), and the optimised production and/or inspection strategy resulting from method step 6) are stored in at least one data memory in a respective memory step and the production and/or inspection orders are generated in method step 2), the production history generated in method step 5e) and the analysis and simulation of production generated in method step 6) on the basis of actual measurement results are stored in at least one central memory in a respective memory step, it being possible to retrieve the at least one data memory and/or the at least one central memory locally.
