Abstract

Systems and methods for retuning a surface to a nominal geometry using local reference points are disclosed. The system can include an imaging device for detecting the location of local features on an object. The system can use the location of local features, as opposed to an absolute reference frame, to determine one or more reference areas and one or more surface defects on an object. The system can then determine a nominal geometry for the surface (i.e., a surface that is substantially free of surface defects) and calculate the tool path necessary to create a nominal geometry. The system can machine the surface and, in some cases, rescan the surface to ensure the operation has machined the part to the nominal geometry.
