  • Roundness standard
    Publication number: 20040075829
    Abstract: A roundness calibration device includes a ring or plug gauge with a wall defining an arcuate surface traversable by a sensing probe. A protuberance, typically in the form of a piston, is displaceably mounted in a radial bore in the wall. A displacement device adjusts the amount of protrusion of said protuberance to locally, radially modify the arcuate surface. A calibrated measuring device accurately determines the amount of protrusion.
