Circularity and cylindricity
WebDefinition of Circularity (Roundness) In 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. WebThe difference between these two measurements is that circularity only measures the 2-D surface of one cross-section at a time. It only measures around the surface of the circle. Cylindricity measures circularity in 3 …
