DIMENSIONAL CAPABILITIES OF STEEL CASTINGS

One very good rule is to allow enough “machining stock” so that the first cut remains below the cast surface on the metal by at least 1/16 in. (1.5 mm). Required machining allowances must be chosen with care. Critical surfaces that are fixtured using as-cast locators are sometimes preferred to avoid excess machine stock on critical surfaces.
