ASME Y14.5-2018 & Single Solution Datum

Hey guys & gals,

Given that ASME Y14.5-2018 was released for purchase about a year ago, I was wondering who (if anyone) works for a company that has transitioned to the latest revision of the standard (Yes or No?)

For those who have, what is your answer for the "Single Solution Datum" for a single plane, multiple datum target planes (e.g. A1,A2,A3, etc), and offset multiple datum target planes.

Thanks 🙂

Y14.5.1 - 2020(?) has yet to be released so anything that people are doing to circumvent this is in violation of the standard, unless you find somebody with a draft of the new 14.5.1 and they have developed a constrained least squares fitting algorithm that is appropriate.

I am curious as well.

I guess I should have dug a little deeper to see if Y14.5.1 had been released, as my source indicated it would. 😃
To be fair, it looks like, for a single A Datum plane, one could theoretically use physical shims for orientation, but that would be hella-tedious for multiple part inspection 🤣 ...Perhaps, the Single Solution Datum method would not apply to multiple Datum A pads, as it would be unlikely to produce a convex form from them(?)

Nothing like releasing a new way to measure/interpret something, but saying to wait a couple of years for the full explanation.

I would say that most people refer to the 1994 definition either way.
