Need a diameter symbol on the inspection report?
Need a diameter symbol on the inspection report?
(OP)
A simple question:
1. Shall we need a diameter symbol on the inspection report?
2. If yes, then shall we need a R in front of a radius measuring data on item 1 and 4? See attached.
I was told ASME will release a standard regarding the GD&T inspection report in 2014, is that true?
Thanks for the help

RE: Need a diameter symbol on the inspection report?
We place symbols where they apply. We have had some customers require it. We've had inspectors decline to buy off parts until our reports included such symbols. I do not know that there is a rule, unfortunately.

Also, do you really measure diameter when using caliper / micrometer? So, your drawing specification has diameter, and your measurement...
RE: Need a diameter symbol on the inspection report?
Diameters should never be measured with a caliper.

Slightly off topic here, I am not sure about this:
"Also, do you really measure diameter when using caliper / micrometer? So, your drawing specification has diameter, and your measurement... smile "
I might missing some information here, but kindly correct me.
If it is Outer Diameter, I think that is fine.
But for Inner Diameter, then I see the potential problem.
RE: Need a diameter symbol on the inspection report?
You cannot be sure the part is actually round using only “across” measurement.
In fact, using “go-no go” gauge may tell you more about “diameter” than measurement.
I would be more worried about specifying HOW diameter was measured, than about using diameter symbol.
RE: Need a diameter symbol on the inspection report?
I think if you use CMM, you could measure few points (not saying scanning method) and obtained the diameter as well as roundness (computed).It is all about how much time/money to spend.
Gauge method is good, but for large diameter, I think this is difficult for handling.
