No Y14.5 version referencing Y14.5.1-2019. And, what is the "single solution"? 3

[Burunduk]

Since both the 2009 and 2018 versions of Y14.5 reference Y14.5.1M-1994 while Y14.5.1-2019 is described in the ASME website as "consistent with the principles and practices of ASME Y14.5–2009", who is supposed to be using ASME Y14.5.1-2019, and what for?

Also, what exactly is the "single solution" for datum stabilization mentioned in Y14.5-2018 and only covered in Y14.5.1-2019 (I don't have the 2019 document)? Is it based on Least Squares or something else?

SeasonLee,
Thanks! This clarifies a lot.
I assume then that the manual "shimming" solution is simply finding the thinnest shim or set of shims that will stabilize the part on the datum feature simulator. What do you think?

I haven't tried the manual shimming solution before, but I think most inspectors will rely on the CMM software to do it.
