The Basics of Gauge UncertaintyHow to certify in-house
Thu, 12/18/2014 - 16:47
All manufacturing companies that get audited require some or all of their calibration certificates to specify the calibration uncertainty. At a minimum, some manufacturers only need certified uncertainty for gauges that are reference standards used…
The Basics of Gauge R&RCollecting the right data and getting correct results
Tue, 11/04/2014 - 09:11
Every manufacturing company that gets audited, anywhere in the world, is required to do gauge repeatability and reproducibility (R&R) studies. In some cases, this one study is the only chance to find unknown problems with measurement quality. (…
How to Use a Bias StudyWhen gauge R&R leaves unanswered questions
Tue, 09/16/2014 - 13:18
Assuming there are still questions about the suitability of a gauge for a particular application after a gauge repeatability and reproducibility (GR&R) study, Measurement Systems Analysis, 4th Edition (MSA-4), published by AIAG in 2010,…
The Measurement Uncertainty Approach to Measurement Systems CapabilityYou might expect this method to give you worse results, but the opposite is true
