Assessing measurement system acceptability for process control and analysis using gage R&R

Abstract

Gage R&R, which stands for gage repeatability and reproducibility, is a statistical tool that is applied to measure the amount of variation in the measurement system which arises from the people taking the measurement and the measurement device. The purpose of conducting the GR&R is to quantify measurement error and to reduce the measurement system variation if it is excessive. In a typical gage R&R study, several operators each measure a selected set of items more than once. This study is pursued in a large-scale manufacturing plant in western Wisconsin in order to evaluate the capability of a set of new measurement equipment that is just purchased by the company. Some potential problems related to the measurement system might be exposed after this study and recommendations would be made in order to achieve a successful quality improvement
