Circularity tolerance explained
WebGeometric Dimensioning and Tolerancing(GD&T) is a system for defining and communicating engineering tolerancesand relationships. It uses a symbolic languageon engineering drawingsand computer-generated … 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. A designer chooses the right callout for an … See more There are many methods to measure circularity. All these methods require some skill and can be difficult to perform in the beginning. The means for measuring circularity are as follows: 1. Using a height gauge 2. Using a … See more We use a feature control frame to apply the circularity control to a surface.
