What is gauge R & R and how its done

Question

Accepted Answer

Gauge R&R is a statistical tool used to determine the measurement system's reliability and repeatability.

Gauge R&R involves measuring the same part multiple times using the same gauge by different operators.
It helps to identify the sources of variation in the measurement system.
The results are analyzed using ANOVA to determine the percentage of variation due to the gauge, operator, and part.
A high percentage of variation due to the gauge or operator indicates poor reliability and repeatability.
Gauge R&R is commonly used in manufacturing and quality control to ensure accurate and consistent measurements.
For example, a company may use Gauge R&R to determine the reliability of a torque wrench used to tighten bolts on an assembly line.
