<p>A method of inspecting gas turbine engine rotor disks for reverse engineering includes establishing a plurality of datums for providing a local coordinate system, establishing rim face and primary rim slot data, manually verifying coordinate measuring machine probe indexing relative to probe locations on a rotor disk, programming coordinate measuring machine probing of the primary rim slot as a function of the manually verified coordinate measuring machine probe indexing along a plurality of scan lines that are substantially parallel to each other, obtaining coordinate measuring machine probing data from coordinate measuring machine probing of a plurality of sample rotor disks, outputting dimension data as a function of average values of coordinate measuring machine probing data for the plurality of sample rotor disks, and outputting tolerance data as a function of dimension data value ranges for the plurality of sample rotor disks.</p> |
