A system for indirectly measuring a geometric dimension related to an opening in an apertured exterior surface of a part such as an ammunition case based on direct measurements of the part when fixtured at a measurement station is provided. The system includes first and second holding devices for holding the part therebetween in a part-retaining position in which the part is firmly held between the devices at its end surfaces. In one embodiment, a portion of each of the holding devices extends into its respective opening in the part-retaining position. The system also includes a head apparatus which has a plurality of radiation sources for successively directing arrays of planes of radiation at the holding devices and at the part, and a plurality of receiver modules for measuring the amount of radiation present in unobstructed planar portions of the planes to obtain holding device and part signals. The system further includes a movable stage subsystem coupled to the head apparatus for translating the head apparatus. The system still further includes a signal processor for processing the holding device and part signals to obtain data and a data processor for processing the data to obtain the direct measurements. The data processor determines the geometric dimensions related to the openings based on the direct measurements.

A method and system are provided for inspecting manufactured parts such as cartridges and cartridge cases and sorting the inspected parts. The system includes an illumination assembly for evenly illuminating a plurality of annular, exterior side surfaces of a part when the part is located in a circumference vision station with rings of strobed radiation to generate corresponding reflected radiation signals. A plurality of imaging detectors in the form of CCD cameras are located at the vision station to generate a plurality of side images. The system further includes at least one side image processor for processing the side images of each part to identify parts having an unacceptable defect. The system further includes a mechanism for directing parts identified as having an unacceptable defect to a defective part area and directing parts not identified as having an unacceptable defect to an acceptable part area.
