Difference between circularity & cylindricity
WebDec 22, 2016 · CNC: Circularity and Cylindricity – the difference. Circularity: Every circular cross section of the part must lie between two concentric circles spaced the ‘circularity’ distance apart. In this example, the circularity is 0.25 mm. All cross sections (like A-A and B-B in the figure) must lie within two circles 0.25 mm apart. Webdifferences and how they relate to one another, we have broken down the terminology for you. Roundness, or circularity, is the 2D tolerance that controls how closely a …

WebSep 14, 2024 · Circularity is a 2D callout that controls only form. It cannot be referenced to a datum axis. Because it will only control form (how round the feature is), for control of cylindrical features we should choose a callout that will also provide control of location and orientation. This is why circularity is mostly used as a refinement.
