Gage Repeatability and Reproducibility (Gage R&R)

Gage Repeatability and Reproducibility (Gage R&R) is a method used to evaluate measurement systems' accuracy and consistency. "Repeatability" refers to the same operator measuring the same part multiple times, ensuring results are consistent. "Reproducibility" assesses whether different operators measure the same part similarly. Together, Gage R&R helps identify if the measurement process is reliable enough for quality control, pinpointing whether variations come from the measurement device, the operators, or other factors. This helps ensure that products meet quality standards by using trustworthy measurement systems.
