WebJul 24, 2024 · This section explains how to properly state tolerances for straightness, flatness, circularity, and cylindricity . These tolerances are used where size tolerances don’t provide sufficient control of the part geometry. Form tolerances are not applicable to datums. Form Tolerances SECTION 6 – ORIENTATION 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.
