A quick R&R Calculator, using the following 3 methods:
|
Instantaneous Method for Automated Test Equipment & CMMs
Suitable for an automated test system or coordinate measuring machine where appraiser
variation is negligible. This calculation method requires only one operator and uses the within-subgroup standard deviation
to calculate the Precision-To-Tolerance (P/T) Ratio.
Based on various Quality Magazine articles John Raffaldi & Steven Ramsier
Short Method (Range Method)
The Short method evaluates the combined GR&R error using the appraiser range calculations. Short method is easy on the shop floor and is used to quickly evaluate if a measurement system has deteriorated enoght to warrant a detailed study.
Based on the 'Range method' or the 'Short method' of evaluating GRR
Gage R: Repeatability Only
This method is used to quickly demonstrate short-term gage repeatability. ‘Reproducibility’ component is not evaluated (hence just one R). It may also be used for quickly comparing different measurement methodologies (such as different clamping locations) during gage system development.
