How to complete gage R&R when you have only a single sided tolerance

[Marc]

The spreadsheet jrubio posted R&R 1 Sheet.xls is outdated. It is not using the correct Kx factors, at least the ones that are in the MSA 3rd edition. According to the 3rd edition you should use the new kx factors and when solving based on tolerance divide the approriate metric by 6*Tolerance. Of course this is for a bilateral tolerance. I'm still trying to find what to do with unilateral tolerances.

Can we have a confirmation on this so the sheet attached can be removed if it is obsolete / incorrect?

llapanowski is correct. This spread sheet still uses the MSA 2nd edition constants for 5.15 stdev.

It should be relatively easy for jrubio to update it to the 3rd edition and repost it.

hi guys,

Please give me some input regarding the format that can be used for the one sided specification for GR&G study. Please see the attachment.

Thanks and regards

I have read entries on one sided tolerance, only using max .###, allowing zero to be either the max or min.

But how does it work when the characteristic is stated min 0.035.

How can this single sided tolerance be introduced in a Gage R&R?
