Gauge R&R (One Equipment, one part, multiple Appraisers)

The BIS.Net Team BIS.Net Team

A Gauge R&R (GRR), is used to study repeatability (by the same operator) and reproducibility (by different operators). Analysis of Variance (ANOVA) method is the recommended option for this type of analysis

There are several types of Gauge R&R analysis that can be performed. This option is applicable when one reference part is used for the study and measured by several appraisers. At the conclusion of the study the analyst will have an estimate of the repeatability and reproducibility and can compare these with the process variation.

Output includes an Analysis of Variance, Reproducibility Chart, a probability plot and a dart board.

The dart board is a great visual tool which enables the analyst to see at a glance how reproducible the measurements are and how good or bad the repeatability is.
