GD&T is not clear to understand??

[Maxxysoze]

In one of my customer drawing he has mentioned it as
1.WHEN INDICATED AT CYLINDER (DIAMETER) "A" AND SURFACE "B" & "C" RUN OUT AT DIAMETER D NOT TO EXCEED .003 T.I.R.
in the Notes.
I need to know the exact GD & T to be followed for this Statement.Kindly Help on this.

 

[CheckerHater]

Me too.

Is it possible at least to have a hint, how part, including surfaces A, B, C, and D looks like?

It may be that A, B & C are the primary, secondary and tertiary datums and total runout of .003 applies to D.

Or maybe something completely different.

This appears to be totally "bogus" FCF. Runout requires rotation around a datum axis, which means only 5 of the 6 total degrees of freedom of movement can be constrained. The FCF appears to control all 6, but we cannot be sure until datum features are presented for review. Do you have a drawing with appropriate views to post?

Rather than ask random strangers on the internet why not ask your customer to clarify so you can provide what they want.

 

[mkcski]

Good point. But considering the note in capital letters, the customer may not know what he/she wants. This is normally my experience.

 

[MintJulep]

Agree.
But as a supplier Max is much better off with an official interpretation from the customer. That way he can say "I made what you asked for in your drawing, as clarified by you." Then if the parts really aren't what's needed Max gets paid for the second set.

MintJulep: I agree, but be sure to get it all in writing and signed by both parties! I've been in these situations and the customer denied the conversation even occurred.
