Cylindricity of a hole
WebThe cylindricity control requires each roundness circular tolerance zone to be on the same straight axis and have the same diameter. Note that doing a 100% inspection of roundness across a surface like this is, arguably, technically impractical (if not impossible), as it requires an extremely high number of measurements (theoretically infinite).
