A Comparison of Measurement System Analysis Metrics: Part 2 of 2

The precision of a measurement system is commonly assessed using a gage repeatability and reproducibility (GR&R) study.  Part 1 of this article discussed metrics used in measurement system analysis. Here, Part 2 compares commonly used GR&R metrics with probabilities of misclassification. Comparison of GR&R Metrics with Probability of Misclassification Using Numeric Simulation A simulation study…

A Comparison of Measurement System Analysis Metrics: Part 1 of 2

The precision of a measurement system is commonly assessed using a gage repeatability and reproducibility (GR&R) study. In Part 1, this article describes available GR&R metrics. Part 2 covers their applicability to two broad cases of comparative study.   Measurement system analysis has been a major part of process characterizations and improvements, with key guidance…
