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 ...

In GD&T, Concentricity can be used to establish a tolerance zone for the median points of a cylindrical or spherical feature on a part. Median Points are two points that oppose each other on the feature. So, for example, imagine the points on a circle that are exactly one diameter apart. perpetrator characteristics of rape
