Radius/Chamfer callout
Radius/Chamfer callout
(OP)
Has anyone out there ever seen (C/R) used as a callout for an optional chamfer/radius? Is it in the standard?

RE: Radius/Chamfer callout
ASME Y14.38-1999 got rid of most / so I doubt it's in the standard, at least any more.
CR could be, change request, combat ready, component repair, continuos rod, controlled rectifier or credit per 14.38
In ASME Y14.5 CR is controlled radius in Fig C-3 and 3-8
Don't see it elsewhere in 14.5 from a quick look.
So I've never seen it and wouldn't necessarily know what it meant if I did.

and NO.

In fact our general note on removing sharp edges is:
REMOVE ALL BURRS AND SHARP EDGES ____ MAX RADIUS OR CHAMFER.
(the ____ gets filled in based on each parts function/size etc)

Hmm, I've kind of learnt the opposite from being burned too many times when trying to help.
Sometimes my guess of what they really want is off too!

RE: Radius/Chamfer callout
I would not add "OPT R.XX" after a CHAM. I think it is unecessary to R a chamfer, unless the design requires one. It would be more difficult to control a R.
I think I would have a genersl note for breaking corners or a MAX R, like R .002 MAX.
I think the safer way to go is if you need a radius, call it out with tol ... same for cham. Don't assume the machine shop will understand.
