Where does it state in the standard ASME Y14.5 that the tolerance in the feature control frame is that total tolerance and not ± tolerance? I have a drawing that calls for cylindricity at 0.0005" but I over heard the engineers talk and mention that its ±0.0005" with a total of 0.001".
The engineer looked up the spec as saw what I was trying to explain and agreed that the tolerance zone is 0.0005 all the way around the cylinder, not one side to the other equaling 0.001". The drawing is being updated to 0.001".....
