In light of a gage R&R that will fail (will post the results when complete) on a $4K that someone in my company decided to purchase without the input of Quality, what has been the worst Gage R&R results you have seen from a gage?
Zeiss Contura G2 CMM was installed in front of a bank of windows about 12' wide and 12' high. In Texas.
Upper upper quality manager in charge of the decision would not change things in the planning stage, despite many many warnings of the effect of the sun on the CMM.
Had to build a wall over the windows after the install, after drastic temperature variations were seen across the measuring volume.
Also had to knock a giant hole in exterior brick wall to bring in the custom cradle that the machine rested on.
(not really gage r&r, but the problems arose during the instrument validation process performed in medical companies)
