WebParallelism is a 3d control feature using entire planes and or datums. Multiple checks from surface to surface and not point to point. Wonspur • 4 yr. ago. Micrometers check from point to point. You could in theory read .2500 across your entire part and it could still be out of parallel because it is bowed or twisted. WebNov 7, 2014 · The only difference is that with angularity your tolerance zone of two parallel planes is basically oriented relative to a datum. It is in effect the flatness of a surface at an angle. The big mistake many people make with the orientation controls is thinking that the tolerance in the feature control frame is an angle [ +/- X deg ]. http://www.toolingandproduction.com/features/2007_December/1207_flatness_and.aspx charlton strange
