Gauge Repeatability & Reproducibility Study (Range Method)

The measurement result variation mainly comes from measuring equipment, operator and product. By performing GR&R study. it can be isolating these primary sources of variations and then can be better judged from the measurement result for the part (product).

• Identify the measurement processes that require improvement.
• Identify the source of measurement errors (observer or equipment), and
• Reduce the risks of wrong decision on the results of measurement.
