I am a little confused on a few things. I am relatively new to R&R's and uncertainty, but thought I could figure it out on my own. I was wrong! First, I know that the more data the better the resluts will be. However, can I use the results of a R&R with 3 appraisers, 3 trials, and 10 parts to represent all personnel (6 total) within a given laboratory? Second, when calculating the measurement uncertainty for a given gage, the budget includes a line item for repeatability, is this purely the gage variability from the R&R or the combination of the appraiser and gage variability? Lastly, where is a good place to find a spreadsheet for calculating gage R&R's? Thanks for the help!
