Aj,
From a calibration novice:
Did you (or you company) write this calibration procedure, or is it from some formally approved calibration standard that might be part of an A2LA or other nationally approved system?
Has it proved out with your registrar/auditor?
Would you use such a radius gage to approve product for final shipment to the customer? (I guess that is tolerence dependant)
A hand held radius gage capable of .0005 discrimination, not with my eyes!
If I had a radius that tight called out on a print I would think about accepting the job first, then probably use A CMM or laser type gage, rather that a handheld.
Not a dig, just looking for more information.
I like CarolX's idea.
