Everyone:
Help me understand what you mean by "calibrate" as opposed to "certify" or "zero out" and also how you relate any of these terms to Gage R & R (MSA)
As I read posts here and in ASQ's Forums, there seems to be a lot of interchangeability of terms far different from my understanding and experience over the last 25 years.
I have hundreds of horror stories about operator-owned personal micrometers which have never, ever been included in organization calibration or certification processes. (Also scary stories about organization-owned instruments.) One guy used his two-inch micrometer to "gently" crack walnuts so the meat wouldn't shatter. Other guys used to crank the micrometer down so hard the anvils left dents in the material (mechanical advantage of a screw is amazing!)
