A system and apparatus for inspecting machined parts and determining out of tolerance parts includes a coordinate measuring machine for providing signals representative of the actual locations, relative to an arbitrary coordinate system, of features to be inspected in or on the part. An input device provides signals representative of the nominal locations and the allowable tolerances therefrom of the features relative to a predetermined coordinate system. A programmable data processor operating under the control of a program processes the actual and nominal location signals and causes a mathematical translation and rotation of the actual location signals to their closest fit to the nominal location signals relative to the predetermined coordinate system. The processor then compares the nominal and closest fit signals and provides difference signals representative of the differences therebetween for comparison with the tolerance signals to provide out-of-tolerance signals when the difference signals are greater than the tolerance signals. An output device provides indications of the out-of-tolerance signals to indicate when parts are out of tolerance and should be rejected.

An inspection system comprising: a coordinate measuring machine for providing actual data signals representative of actual feature coordinates on a part being inspected relative to an arbitrary coordinate system; data input means for providing nominal data signals representative of nominal feature coordinates on the part relative to a predetermined coordinate system; a data processor responsive to the nominal and actual data signals to process the actual data signals to provide true position data signals representative of the actual feature coordinates repositioned to most closely correspond to the nominal feature coordinates in the predetermined coordinate system; and data output means responsive to the true position data signals to provide an output representative thereof.
