The cylindricity of a part may be inspected as follows: 1. Place the part on a turntable whose axis matches that of the part. 2. Place a measuring instrument in contact with the surface. 3. Rotate the part to measure deviation along the circle and the probe must be moved up and down so the entire surface is swept..As basic dimensions are perfect, there would be no deviations, and they would not be recorded on the report. Instead of basic dimensions, we would report the following: Flatness for Datum A.
