Dear All,
I am really new for Gage R&R during try to calculate, I found K1 K2 and K3 different constant values. (See picture)
I am not so sure which one should be the correct choice using for verify %GR&R, please kindly clarify for me.
Thank you very much.

Hi Chooty and welcome to the Cove,

In previous versions of the AIAG manual on MSA studies they worked with the higher constant values and calculated the gauge R&R in relation to the width of the tolerance.
In the latest versions however they worked with the smaller constants and calculated in relation to 1/6th of the tolerance.

Hope this helps you

Best regards,
Antoine
