Cylinder out of round tolerance
WebDec 18, 2014 · Cylindricity is a 3-Dimensional tolerance that controls the overall form of a cylindrical feature to ensure that it is round enough and straight enough along its axis. Cylindricity is independent of any datum feature the tolerance needs to be less than the diameter dimensional tolerance of the part. http://www.thehemi.com/forums/viewtopic.php?t=3515

WebRoundness is a comparison of a measured data set to a best-fit circle, i.e. a two-dimensional shape. A roundness measurement is a property of a circular profile in a given 2D plane. So you can for instance talk about the roundness of, say, a 3D cylinder, but this is not the same as cylindricity, which is measured simultaneously at every point ... Webcontrol radial deviations on parts having a round cross section. To help you better understand the differences and how they relate to one another, we have broken down the terminology for you.
