The gage R&R folio is used to estimate the precision of a measurement system, or the system's ability to produce the same value when used to measure the same part multiple times. Precision is defined in terms of repeatability and reproducibility (R&R).
Repeatability is the variation in measurements when the same operator measures the same part multiple times with the same gage. If this variation is too high, then the gage may be unacceptable.
Reproducibility is the variation in measurements when different operators measure the same part multiple times with the same gage. If this variation is too high, then the operators are not using the gage in the same way.
To add a gage R&R folio to your project, choose Home > Insert > Gage R&R, or right-click the Test and Planning folder on the current project explorer and choose Add Measurement Systems Analysis > Gage R&R on the shortcut menu.
