Abstract

Reliable measurement systems are essential for the success of an organisation. Gauge repeatability and reproducibility (GRR) studies assess this measurement system's capability. This paper demonstrates the application of GRR study in a Quality Control Laboratory, where measurements from three precision measuring instruments were analysed using: AIAG for GRR X / R and analysis of variance (ANOVA) methods. It then delineates the major observations in a medium of analysis (MS Excel and Minitab). Previous similar studies were extensively referred to draw conclusions. Findings revealed that part variation correction factor becomes crucial for instruments with high repeatability error. Reliability of X / R method was also assessed. Moreover, it was found that the % GRR study variation and number of distinct categories (ndc) are not coherent for X / R but are coherent for ANOVA.
