WebMay 6, 2024 · Concentricity considers how a cylindrical shape is positioned on a theoretical axis. In contrast, the runout considers how the target deviates from the dimensions of a circle when it is perfectly positioned on the rotation axis. However, when the part is measured using a similar cross-sectional plane, this is considered a case of coaxiality, as ... WebDec 21, 2014 · Circularity is measured by constraining a part, rotating it around the central axis while a height gauge records the variation of the surface.

WebDec 28, 2024 · A single part may have multiple features toleranced by GD&T. Each feature’s tolerance is represented by its own FCF. The FCF connects to the feature under control or … Circularity can be measured using a turntable and a height gauge. To measure circularity, we carry out the following steps: Fix the part in a turntable (or a vee block) and constrain it so that it rotates along the central axis. Select a cross-section and set a height gauge probe at this cross-section.
