Abstract: Systems and methods of inspecting a manufactured part include creating a computer model of the part with a desired model contour having a model feature at a desired location. The manufactured part is scanned to obtain scanned data indicative of a manufactured surface formed in a manufactured contour and having a manufactured feature at an actual location on the manufactured surface.

A determination whether the manufactured part is acceptable is based on a comparison of the actual location of the manufactured feature with and the desired location of the model feature with the model surface in the modified model contour. Additionally or alternatively, the reaction forces are compared with a reaction force threshold to determine whether the manufactured part requires reworking.
