Someone explain these dimensions?

[Underspec]

Someone explain:

#9 - ?

#11 - ?


Wondering if I'm correct on the interpretation. FYI, uses Ansi Y14.5M-1982.

[Matthew D. Hoedeman]

Well, without seeing more of the drawing, #11 is surface checks, +/-0.5 tolerance

#10 looks like the width of that indent has a minimum and maximum width.

[russ.griffith]

I would agree with Matt

[Underspec]

How would you check that surface ??

[tking]

I would agree with Matt

Me too.

Do you have a CAD model?

[Underspec]

No CAD model. It's a fairly large part that would require a fixture if used on the CMM.

[russ.griffith]

If that's all the information the drawing gives you, you will most likely need the cad model. Or someone will have to give you xyz coordinates to take your hits, but that too will require Cad.

I agree with Matt. Except ablieve he means #9 and it is Metric and [inches]

[Matthew D. Hoedeman]

Yeah yeah yeah, maybe I should pay closer attention to what I am doing.

[MJBolster]

If I had to use this drawing, referring to #11, I would consider that the profile of the indicated surface would need to relate to datum A within a tolerance zone of 1 ( inch or millimeter- whichever applies). The drawing section isn't enough to figure out what the target feature is. #9 looks simple enough.
I think I'm in agreement with MATT.

[djayne]

#11 is definately Profile and Location back to Datum -A-. We have this on all of our manifold drawings. Let me ask my GD&T guru about #9 and get back to ya.

[djayne]

He says the same thing about #9 it's the width of the indent in both metric and inches. Can you show a little more of the profile area?

*About #11 I agree with Matt it is a slot or gap wit min & max width.
* In order to check the profile for # 9 without cad modle, first, take multiple point for that surface and and construct a PLANE out those point, let us say that surface laying on z plane , then take some indivitual points as measuring points ,and compair them with the original plane you made in z direction , so your measured points should br within -/+0.5 of the z reading of the constructd plane.

Best regards,

I agree with everyone about # 9. Now # 11 is a profile which appears to be on a curved surface and it has the circle around the pointer which means all around. I think you need more of a Datum scheme to check this without cad.
