A shout to the experts here,
Have been asked to help with a tool shop overall R&R on all of their various gauges.
I am going into this task thinking that a minitab driven, Anova study, with %Tol as the qualifier, will be an acceptable R&R.
However, I am torn between the %Tol, or the % study Var being used as the final result.
As this is not a "process control situation" and more of a "does this tool meet it's specification" issue, am I correct in assuming that all that these studies need to encompass on a pass / fail basis would be the %tol in a Gage R&R study?
I know you can lump gages into a "family" situation...i.e. 6" caliper is a 6" caliper...but how much do we have to go into qualifiying this same 6" caliper when it measures one cavity of a certain tool that is 1" in diameter with a +/-.020" tolerance, as opposed to the same tool measuring a 4" cavity with a +/-.020" tolerance?
Does the calibration cover this if it is done effectively to rule out any linearity issues?
Also wanted to know the opinion of the group as to whether or not this would be an acceptable situation for using an X-Bar R method for the R&R. Toughts on why or why not would be appreciated.
As always, your superior guidance and wisdom is much appreciated.
Also,,,how do you add the cool quotes to the bottom of your posts? I have searched the user CP and have not found this..?
