Circularity tolerance explained
The geometrical tolerance of circularity is one of the four types of form control, the others being straightness, flatnessand cylindricity. Also known as roundness, it control’s a feature’s circular nature such as the diameter of a cylindrical pin or a hole. The aim is to set a limit to the desired accuracy of the circular … See more The circularity callout defines a two-dimensional tolerance zone for the actual part surface. The tolerance zone consists of two concentric … See more Circularity may sometimes be confused with other callouts. Each callout has a specific function and a method of measurement.

Circularity tolerance explained
Did you know?
WebRoundness, or circularity, is the 2D tolerance that controls how closely a cross-section of a cylinder, sphere, or cone is to a mathematically perfect circle. Consider a cylinder whose purpose is to roll along a flat surface. A small flat on the OD of the cylinder would detract from how smoothly the shaft can roll.
