Hi there,

I appreciate if you could make some comments on this result:

One sided tolerance Cylindricity

% Contribution: 0.55 % (% Study Var: 7,08%)

% Tolerance: 2,85%

ndc: 19

But one part is outside control limt (R-chart)! Can not see the cause.

Parts 5 and 6 both display higher ranges. Is it possible that what you are seeing is Within-Part variation rather than gage variation?

It is a CMM and i think it is more within-part variation that has caused this rather than gage variation. So from my point of view i do not think we have to do a new MSA study again. If not anyone in this forum disagree and has good explanations for the outliers of course...
