WebFeb 12, 2024 · The short answer is no; that method does not provide the correct value. We will explore this issue in detail below. Circularity is a form constraint that measures how well the shape of a part matches a perfectly circular shape. This constraint is sometimes referred to as roundness. 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.

WebIn GD&T, Circularity describes how close an object should be to a true circle. It is also sometimes called Roundness. Examples of features that might have Circularity controls would be cylinders, spheres, and cones. For moving parts, circularity is often used to help ensure the parts move smoothly and wear evenly.
