... ∅.5 01 + ∅.005 = ∅.5 06. The hole has an MMC size limit of ∅. 511 and a positionaltolerance of ∅.005 at MMC. Since it’s an internal feature of size, its virtual condition is ∅. 511 − ∅.005 =∅.5 06. ... zone shrinks to the specified diameter (∅. 010 ). Conversely, asthe pin’s actual mating local size approaches LMC (∅. 062 ), the tolerance zone expands to ∅. 011 . Eitherway, for any pin satisfying both ... virtual condition boundary as described in section 5 .6. 3 .1 and Figs. 5 -17 (b)and 5 -18 (b). Alternatively, the “center method” described in section 5 .6. 5.2 may be applied to a flatnesstolerance at...
