Abstract

A system and method for numerical control processing of an in-process part. A mathematical mapping is generated which approximates the deformation of the in-process part as measured against a nominal model. The mapping is applied to nominal NC tool paths to generate modified tool paths that travel in the distorted coordinate space of the in-process part. A result is that local features may be machined into the in-process parts in reasonable locations, and non contact measurement systems as well as surface finishing systems can travel at a more constant distance from the surface of the in-process part.
