Circularity and cylindricity
WebY14.5M-1994 [6.4.3], Y14.5-2009 [5.4.3] The cylindricity tolerance can be used with cylindrical features only. The tolerance will be on a leader line which points to the cylindrical feature. Cylindricity is also very difficult to measure without the aid of a computer. Both circularity and cylindricity require sweeping the surface to get many ... WebDec 21, 2014 · Circularity is a very common measurement and is uses in all forms of manufacturing. Any time a part needs to be perfectly round such as a rotating shaft, or a bearing, circularity is usually called out. …

It only controls the "exterior" of the surface. The "tolerance zone " is 2 concentric "cylinders" .0005 apart from each other. Page 96 on y-14.5 2009. I would probably use a form only profile callout as reference but thats just ...
WebCylindricity is commonly used for parts like pins that must have good circularity and straightness. The advantage of using Cylindricity over, say, Circularity, is that … WebJan 8, 2016 · Cylindricity: Every circular cross section of the cylinder must lie between two concentric cylinders spaced the ‘cylindricity’ distance apart. In this example, the cylindricity is 0.03 mm. All cross sections (like A-A and B-B in the figure) must lie within these two cylinders 0.03 mm apart. Cylindricity is 3-dimensional.

Thus, cylindricity controls the entire surface as opposed to a single cross-section in circularity. What is meant by roundness?
WebOct 22, 2024 · Circularity is a perfect circle, while cylindricity is an imperfect circle. The difference between these two types of circularity is the amount of distortion in the shape. Cylindricity is more distorted than circularity, meaning that it is not a perfect circle. How to measure circularity and cylindricity
