Circularity tolerance explained
WebJun 21, 2024 · The tolerance zone is made of two parallel lines that follow the true profile in either direction. Unless stated otherwise, these parallel lines are assumed to be equidistant from the true profile. The distance between the two parallel curves is the tolerance limit. 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.

WebApr 1, 2024 · Circularity refers to how close the cross-section of the workpiece to the theoretical circle. When the difference between the maximum radius and the minimum radius is 0, the circularity is 0. 1. Circularity is a 2-dimensional tolerance zone, which consists of 2 concentric circles whose radius spacing is equal to the tolerance value.

WebApr 22, 2024 · It involves determining the wall thickness — the measurement between the outside diameter (OD) and inside diameter (ID) of a tube — at different points to see how constant it is in relation to a central axis. The challenge lies in establishing a theoretical central axis that serves as the reference point (datum axis). WebDec 9, 2024 · This defines a circular tolerance zone of the radius 0.5 mm around the true position. The axis of the manufactured feature must lie within this ⌀1mm circle, meaning the maximum distance from the intended axis spot is the same in every direction.
