ABSTRACT:
A method is disclosed for using a numerical method such as finite elements to adjust a model of an object for use with computer integrated manufacturing. The adjusted model is useful in correcting errors introduced in manufacturing. The method requires the model to be available in an electronic form. An object produced based on the model is measured to produce an electronic facsimile. The two electronic representations are then correlated and some differences between them are found. With one or more of the differences, a phenomenon that would have caused the difference(s) is determined and applied in an inverse manner to the model. A system for carrying out the invention is also disclosed.
