Abstract:
A system for NC processing of an in-process part, comprising:a nominal model of the in-process part;means for measuring a series of n points on the in-process part;a processor for generating a deformation model that approximates deformation of the measured part relative to the nominal model, the processor comprising:means for determining a plurality of mapping functions for mapping point locations from the nominal model to approximate measured locations of points on the in-process part;means for optimizing the plurality of mapping functions to minimize the distance between the point locations from the nominal model to the measured locations of points on the in-process part; andmeans for transforming the point locations from the nominal model to the measured locations of points on the in-process part according to the plurality of optimized mapping functions; anda computerized numerical controller for controlling the processing of the in-process part according to the deformation model.
