My appologies for the very generic post, but I've been reading these forums, and often feel that I'm completely lost.
To begin, I was hired as a CMM programmer, aparently in my employers view, that makes me the quality manager and responsible for obtaining ISO17025.
Note: We are limiting the scope to our dimensional lab, and our calibrations are done by an outside 17025 source.
If anybody has some examples of how they calculated measurement uncertainty for: micrometers, calipers, height gage, CMMs, indicators, and gage blocks(for these I was just going to use the statement on the calibration statement since they are just used to set a indicator when we measure with them), you'd really be helping out someone who's in way over their head.
Measuring I'm alright at, but this paperwork is driving me mad.
Would taking the listed uncertainty on my calibration statement then running 10-20 measurements on a known standard, calculating the SD of that, and adding that to the inherant uncertainty(via the statement) be accurate? That would seem to be a lot of double dipping and may give me some awefully high numbers.
Any links, book recommendations, reading lists, etc are highly appreciated. If anybody is in the DC/Baltimore/Harford County MD area, drinks are on me if I get to pick your brain a bit!
My sincerest appologies for basically spamming a very nice forum, but, I figure I'll ask before I give in.
