What is Understanding GD&T Circularity Tolerance about?

Circularity controls how close an object is to a true circle. It ensures a cylindrical or round feature is not too oblong, square, or out of round. Circularity is measured by rotating a part and recording variations in height with a gauge. It allows for looser diameter tolerances by controlling the roundness of features like holes and shafts. Circularity specifies a tolerance zone between two concentric circles measured perpendicular to the central axis.
