Name for Other Zone
Name for Other Zone
(OP)
Hi All,
Here's a fun one.
If the place that the feature is allowed to be in is called the "tolerance zone", what should we call the place that the feature is not allowed to be in? Functional gage components, for example, would occupy this other place.
I have a couple of possibilities, but I'm wondering what others think. Any ideas come to mind?

As far as I understand, an envelope is something different. It's a zone that the as-produced feature fits into, like an actual mating envelope.

I agree that the place where the feature must not lie can be pretty big. It really is the rest of the universe.
There are also cases where the tolerance zone is most of the universe, and there is only a small volume where the feature is not allowed to go. One example is a Position tolerance referenced at MMC for a hole, that defines a virtual condition boundary that the surface is not allowed to violate. The tolerance zone is the infinite volume outside the VC boundary, and the "other place" is the relatively small finite volume inside the VC boundary.
If the feature extends outside of the tolerance zone, past the boundary, then it's ... out of bounds?

I was thinking of just one tolerance.
The "other place" I'm thinking of is the complement of the tolerance zone. The remainder of space, if you will, that the tolerance zone doesn't take up. There doesn't seem to be an existing term for it.

Resultant Condition Boundary? This was supposed to be a fun thread. ;^)
I'm not sure about your interpretation of the RC boundary. I don't see the RC boundary as part of the Position tolerance requirement - it's just something that can be calculated. I'll go out on a limb here and say that the feature can violate the RC boundary and still pass the Position tolerance (it would fail the Size tolerance).

I will refrain from further comments about Resultant Condition, I promise.

Thanks. We can debate the Resultant Condition thing in another thread if you like. I haven't agreed with you yet ;^).

Yes, that's it! I thought of that myself, but I was waiting for someone else to suggest it so I wouldn't be the only one ;^).
