GR&R STUDIES (MEASUREMENT SYSTEM)

Quality Tools & Techniques

Introduction

GR&R Studies is a method for evaluating and quantifying an existing gauge or inspection system. It determines if an inspection method or equipment produce acceptable, marginal or unacceptable results. It is often taken for granted that inspection results are true values with no errors. In reality, all inspection or gauge results are subject to variation. It is a required component for calculating process validation, and the acceptability level for a production process.

Application of Gage Repeatability and Reproducibility (GR&R) Studies can give rise to the following benefits:

  • A criterion to accept new measuring equipment.
  • A comparison of one measuring equipment against another.
  • A basis for evaluating a gauge suspected of being deficient.
  • A comparison for measuring equipment before and after repair.
  • Assess the impact of GR&R on Process Capability Studies.
