A GD&T question for Profile

[[Ri...]]

I have a print where non-toleranced features fall under Note 7.

Note 7 is a profile of Unequal Distribution .040/.010

Then there is Note 17, which allows for a surface condition.

See attached image.

How do I implement Note 17 in the Profile requirement?

Edit: 

I am unable to find a single instance where Flag Note 17 is applied to a feature.

All Notes are "Unless Otherwise Specified".

Now I wonder if Note 17 is a general note and not applicable on this particular blueprint.

Never had something like this before. 

 

I would measure the depth of surface texture (value below 0,015) and hope that it is quite uniform and put it on the tolerance (additive).

Now do you put it on the tolerance out or in the material or 50/50?

This is pretty much impossible by the info given alone. One could decide depending on how the texture is achieved. Is something added to achieve the texture or is something removed to achieve the texture?

 

Thinking about the wording ... I would read "in addition" as additive material wise (non native speaker).

Note 17 displays the .015 allowance as a stock added condition.

If the surface texture has not been applied to the part yet, then I would ignore the note entirely. I'm assuming this note is to control surfaces that get powder coating / paint, so it is an N/A situation if the inspection is being performed prior to coatings.

Maybe I should have included this note. 🫤

I think Note 9 applies to Note 17.

Snippet from the print, initially I read this as two separate instructions.

Now I am leaning on the Note 9 is a construct of how Flag Note 17 is applied where applicable while Note 9 may encompass any feature on the part generated under the instruction.

Note 9 is a general note falling under the initial heading above the notes "Unless Otherwise Specified".

Note 17 is a flag note.

Would the .015 tolerance be treated like a dynamic profile?

Haven't thought of that, and I would not know how to apply it in v2022.

Is this a capability that v2025 has?

I reread the dynamic profile section, and I don’t think my suggestion works for this part since the note says MAX and "MEASURED SURFACE". I think reporting profile with no datums and a unilateral tolerance zone in the + material direction would satisfy Note 17.

This isn't clicking in my brain.

If I do not use datums, then I am violating the required DRF.

So I looks like they expect a very rough surface texture and they want a .015 band of surface variation ignored. If that's the case, then I think you want some type of data filtering to happen.
