WebJan 26, 2024 · For example, if A and B are the short axes at the ends of the part, then they may be used simultaneously to inspect other central part features by combining A and B in the datum block as A-B . Why Use Circular Runout? As mentioned earlier, circular runout is a combination control, determining a combination of features for a part. WebThe first feature control frame contains a symbol that represents the geometric characteristic to which a tolerance is being applied, for example, location, profile, form, orientation, or runout. Form tolerances control straightness, flatness, circularity and cylindricity; profiles control line and surface.
