"WebDec 18, 2014 · Cylindricity is a 3-Dimensional tolerance that controls the overall form of a cylindrical feature to ensure that it is round enough and straight enough along its axis. Cylindricity is independent of any datum feature the tolerance needs to be less than the diameter dimensional tolerance of the part. " - Circularity vs roundness gd&t

Circularity vs roundness gd&t

WebThe difference between roundness/cylindricity and circular/total runout is twofold. Firstly, in a cylindricity or roundness check the tolerance zone is free to rotate, but with runout checks the tolerance zone must be centred on the axis. WebApr 22, 2024 · While cylindricity is an indicator of roundness and straightness along the full axis of a 3D part, concentricity compares an OD and ID or compares roundness at two different points. Sometimes called coaxiality, GD&T concentricity “controls the central axis of the referenced feature, to a datum axis” according to the website GD&T Basics.
