  • Hole profile gaging systems
    Patent number: 5010658
    Abstract: The present invention provides a hole profile gage comprising a probe that senses deviations in the contour of the inner surface of a bore while it is retracted through the bore. The profile gage includes a processing unit that samples the output from the probe, develops a profile for the hole, and evaluates whether the profile is within predetermined tolerance limits. In a preferred embodiment, the probe comprises a split ball probe coupled with a transducer. In use, the probe is retracted through the bore by a spring coupled with a damping device.
