WebNov 15, 2024 · The flatness tolerance zone consists of two parallel planes that create the boundary within which all specified surface points should lie. This is what is shown on the … WebThe Flatness form tolerance controls the shape of a planar feature without controlling the orientation or location. The surface of the considered plane must lie within a tolerance zone bounded by two parallel planes, which are separated by a distance equal to the specified tolerance value. In addition to overall flatness, you can also specify ...

WebJun 3, 2024 · The cylindricity tolerance zone is similar to flatness – if the flatness tolerance zone was wrapped around the surface of the cylinder. So this block states the tolerance value for the feature. This value is the radial separation between the two coaxial cylinders of the tolerance zone. WebThe tolerance zone is defined by two offset curves unless otherwise specified. Surface Profile creates through two offset surfaces between which the feature surface must fall. This is a complex control typically measured with a CMM. Orientation controls concern dimensions that vary at angles, including: sydney company
