Gage Repeatability and Reproducibility (GR&R)

Gage Repeatability and Reproducibility (GR&R) - The evaluation of a gauging instrument's accuracy by determining whether its measurements are repeatable (there is close agreement among a number of consecutive measurements of the output for the same value of the input under the same operating conditions) and reproducible (there is close agreement among repeated measurements of the output for the same value of input made under the same operating conditions over a period of time).

Gage R&R - Gage R&R, which stands for gage repeatability and reproducibility, is a statistical tool that measures the amount of variation in the measurement system arising from the measurement device and the people taking the measurement.

G R&R - Gage Repeatability and Reproducibility tells about the statistical properties of repeatability & reproducibility and reveal the capability of the gages and users - not the statistical properties of the complete measuring system. To learn more about the measurement system, evaluate system bias, stability and linearity. Use well calibrated gages for the study.
