Abstract

See full text

Determining position parameters defining relative position of a manufactured derivable surface relative to a reference surface, the process comprising: providing a nominal surface expressed in a nominal frame of reference and corresponding to the theoretical derivable surface to be manufactured with the nominal value of the position parameters defining the relative position of the nominal surface relative to the reference surface, providing a measured surface of the manufactured derivable surface expressed in the nominal frame of reference, providing at least one deformation surface defined by at least one deformation adjustable parameter, determining a composed surface by adding the measured surface and the deformation surface, determining the position parameters and at least one deformation parameter by minimizing the difference between the nominal surface and the composed surface.
