Hello Folks:
very glad to discuss with u all here .
Our product were tubes and one of the charicteristics is wall thickness .when I did the G R&R, I can`t fix the point the appraiser measured on the tube axis ,so the result of the G R&R report is not exactly the same as it did in the plants.
I have seen one way of calculating WIV but only if there were maximum and minimum measured ,this method comes from the 2nd edition of the MSA manual.
And I can`t find any formula in the third edition MSA Referenced Manual except a short explain in words.
Can anyone give any suggestions or the method for calculating With-in part var ? Thank you in advance !
