Hi! i jsut learn MSA and want to use GR&R analyze 7 machine
but common practice which i found in training room and template format just only for 2 or 3 appraisers (by average and range method)
Can i analyze gage R&R with 7 appraisers/machine?

Thank for help,

Yes, you can. Most Excel based MSA templates were designed for three appraisers, so this would limit you. However, software packages such as Minitab will normally allow more than three appraisers. I just checked with Minitab, and it allowed me to add 23 appraisers before I stopped.

Normally, there is little benefit to using more than three human appraisers provided they were randomly selected. However, if your appraisers are machines, which I inferred from your wording, I would definitely want to include all of them.
