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. WebCompared to cylindricity in GD&T, circularity tolerance application is to control critical features only. For example, circularity tolerance controls hole inner diameter and shaft outer diameter. It gives more flexibility to the manufacturer while meeting the part functional requirements. Click here to read GD&T Interview Questions and Answers
