Gage R&R (Gauge Repeatability and Reproducibility)

Gage R&R (Repeatability and Reproducibility) is a method used to evaluate how consistent and reliable a measurement system is. It assesses whether a measuring instrument (like a tool or device) provides repeatable results when used multiple times under the same conditions (repeatability) and whether different operators or setups produce similar measurements (reproducibility). Essentially, it helps determine if the measurement process can be trusted to accurately reflect the true value, ensuring quality and minimizing errors in manufacturing or inspection processes.
