Hi,
I have some questions about different subjects treated in the MSA manual:
1) In the Average and Range Method at pag. 116, they say that if the analysis is based on the tolerance to evaluate %GRR, ecc it has to be divided by 6.
In the ANOVA method after calculations I have the GRR = 5,15*sigma. To calculate the %GRR I can use the tolerance or there are problems?
2) When I calculate the %GRR for attribute measurement systems with the Analytic Method, can I use both the tolerance or the total process variation? Or can I use only the tolerance?
3) I need to do a flow chart of the controls that an organization need to do to its measurement systems. I know that stability must be done for first, but what about bias, linearity and GR&R? One must be control before the others?
Thank you very much

) but I just looked for it
on this forum and found out an interesting topic about MSA and stuff:
