Comments on: Gage R&R For IR Thermometers? http://measurementblog.com/archives/47 Measurement devices, measurement education & measuring Thu, 16 Oct 2008 01:52:42 +0000 http://wordpress.org/?v=2.6 By: admin2 http://measurementblog.com/archives/47#comment-267 admin2 Tue, 11 Sep 2007 20:48:55 +0000 http://measurementblog.com/archives/47#comment-267 Mr, Abrams: Thanks for your comment. I'll have a look at your email later today and perhaps respond directly. You have illustrated part of the problem of setting up a meaningful Gage R&R test; one needs multiple repeats with multiple operators to measure results from multiple objects that are different in the parameter you wish to measure. The questions about how much of each and how repeatable each is will be answered by the measurement results, correctly analyzed. Minitab should do the analysis "with its eyes closed".. The purpose of the Gage R&R test, as I understand it, is to separate and quantify the two major sources of measurement variation, the equipment and the operators. But the measurements need to also be under conditions that are highly repeatable and stable to begin with. Sounds like something is changing and you are not fully aware of it. Maybe, maybe not; I'll check your email for details. Mr, Abrams:

Lets say a flir a A20M, with an accuracy of +/- 2%. I have performed repeated tests with the camera to find the % process using minitab at a passing level when our samples are kept in the same spot. When we remove our samples and replace them, our process fails dramaitcally. -James Abrams I sent you an email and I am very interested as to how you commence a gauge r&r with a IR camera.

After two months, yours is the only comment that even hints at an interest. Anyone else? There's less than a month left! GRP I also said I would spend the time to do it if there was enough interest by September 20, 2007.

After two months, yours is the only comment that even hints at an interest.

Anyone else? There’s less than a month left!
