  "abstract": "This disclosure describes an in-line metrology station designed to separate measurement errors originating from a part from those originating from its supporting fixture. The system employs a reorientation mechanism to present the part-fixture assembly for measurement in at least two distinct orientations. A data processing unit then applies arithmetic calculations to the multiple measurement datasets to mathematically isolate the contributions of the part's geometry from any systematic deviations introduced by the fixture. This approach mitigates the misattribution of fixture-induced measurement deviations to the manufactured part, enabling targeted intervention for fixture service or part rejection.",
