It says that the feature is to be measured and be at True Position within a 0.04 diameter with respect to Datums A, B, & C at Maximum Material Condition (smallest hole, largest part) - and - True Position within a 0.015 diameter at MMC to datum A.
Either the A datum should be removed from the top FCF or the bottom FCF should be eliminated.
Edit: Although it could be argued that it 'might' be physically possible to satisfy both FCFs logically depending on the geometry involved.
Since it's a single position tolerance, it is called a composite tolerance. The upper segment controls location and orientation of features to specific datums and the lower segment controls both location and orientation between the features BUT orientation only to the specified datums. Wow, that's been a while since I used that part of the grey matter. Need some brushing up because I had to look this up.
It means that the upper segment is the pattern locating with a .040 positioning zone and the lower is the feature locating with a .015 zone. I'm guessing that this is a hole pattern for one part to be bolted down to another?
I am assuming that Datum A is a surface that is perpendicular to the axis of the hole that is being tolerance.
If that IS the case, then you can picture this as a cylindrical tolerance zone (that essentially controls perpendicularity) of diameter .015 that floats within another cylindrical tolerance zone of diameter .040. Both must be true at the same time.
The bottom one is essentially a refinement of the top one.
The top one controls orientation, position and location, while the bottom one really controls perpendicularity.
Here's another one:
Looks like I was a little bit off....oops! *grin*\
Thanks for asking the question! I got a little refresher!
I have never come across composite gtols before, in all my years of mechanical engineering!
By the way, the one I marked was not the only Correct Answer, but I had to choose one...
