What does R&R stand for?

[ILLUSTRATION OMITTED] For example, if an OEM provides a CM with 300 control dimensions for 35 drawings, it's likely that the OEM will want the official control plan to include: * How the CM will measure each one of those dimensions; * What instrument the CM will use to measure the dimensions; * The number of parts to be measured; * If a Gauge Repeatability and Reproducibility study will be performed; * If the CM plans to do a 100 percent inspection or statistical process control (SPC); and * If installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) validation was done, what equipment it was done on, and when.

Individual factors included in the expanded measurement uncertainty metric are gage repeatability and reproducibility (GR&R) variance, nonlinearity, resolution, hysteresis and artifact uncertainty.

PROCEDURE FOR AN ATTRIBUTE GAGE R&R STUDY An approach commonly used is a repeatability and reproducibility (R&R) study.

NEW OR REVISED TECHNICAL INFORMATION PAPERS (TIPS) Technical Information Papers: * TIP 0304-72 How to perform a gauge (instrument) repeatability and reproducibility study (measurement/range type) All individual TIPs or Test Methods are available for electronic or paper delivery.

The maximum experimental repeatability and reproducibility of the algorithm can be tested without influence of other factors such as an error introduced by the peel test procedure (described later).

Laboratory testing uses specialized environmental chambers and artificial light sources that provide excellent repeatability and reproducibility, as well as much faster results than real-time testing.

The key topics are gage repeatability and reproducibility, Six Sigma, Total Predictive (or Productive) Maintenance (TPM), 5S process improvement methodology and variation and how it impacts the manufacturing process.
