countersink callout
(OP)
I have a customer drawing with a counterisnk callout that uses 'VD' after the dimension. What does 'VD' mean?
Thanks

RE: countersink callout
Does the value of the dimensin correspond more closely to a diameter or to a depth?
RE: countersink callout
"90º C'SINK TO *.28-VD" (* = diameter symbol)
Quite clearly a letter 'V' and not the angle symbol. So they give the angle AND the diameter and then add "-VD"
weird, huh?
I'm stumped - the old books say that 'VD' = Van Dyke!

She says that guy went out in the shop and asked. She was told that it stood for "Visuallu dull" as in break edges.
Think someone's pulling her leg? I do.

I would remove it and just call out the depth/angle. If the surface roughness needs to be something special, it needs to be indicated.

RE: countersink callout
You'll find lots of seeming experts on D&T in this forum. Years ago I learned that there are reams of people who are convinced that "their way" is the "right" way or the only way to do it. When in doubt I simply go to ASME Y14.5M-1994 and all the other ASME standards. I am not shy about leaving behind all those self-proclaimed experts in favor of going to the "horse's mouth" of ASME standards. As for abbreviations such as VD I would first go to ASME Y14.38 ABBREVIATIONS. If you don't have Y14.38 then MIL-STD-12 is practically identical and available for free on the Defense Logistics Agency's free ASSIST on-line document server.

Ease up a little. I haven't seen any posters claiming to be experts on this forum. I am often given new insight to Y14.5 through this forum. I agree that ideally the standards should be followed, but this isn't an ideal world. KimBellingrath had a question that is not addressed in ASME Y14.5.
If this abbreviation was covered by these standards, this would have been a very short thread, but it isn't, so we are just putting out suggestions on what the abbreviation may mean. Just because the abbreviation isn't listed in the standards doesn't mean it should be ignored without trying to determine it's purpose and meaning.
