Six Sigma Gauge study -Gauge R & R
Content Repeatability and reproducibility (Gauge R&R) Using Minitab
Repeatability The variation in measurements obtained with one measurement instrument when used several times by one appraiser while measuring the identical characteristic on the same part.
Repeatability An operator measures a single part with Gauge A 20 times, and then measures the same part with Gauge B. Gauge A Gauge B
Reproducibility Variation in the average of the measurements made by different appraisers using the same measurement instrument when measuring the identical characteristic on the same part
Reproducibility Operator A Operator B Operator C The reproducibility is poor!
Gauge R&R study 10 pumpkins measured by three people twice each using the same measuring tape
This graph represents: GR&R Average The Gauge R and R variation for a number of people, measuring the same part many times with the same instrument.
