ASME Y14.45-2021 is Now Available

[axym]

Hi All,

I am very pleased to announce that the long-awaited ASME Y14.45 standard for Measurement Data Reporting has finally been published!

The primary objective of Y14.45 is to provide standardized definitions and formats for reporting GD&T measurement data. This standard is necessary because the well-known ASME Y14.5 standard for Dimensioning and Tolerancing only defines conformance in terms of pass/fail requirements - tolerance zones and acceptance boundaries. Extracting numerical measurement data from these GD&T characteristics has proven to be a very different challenge. We made a real effort to address difficult topics such as profile reporting, MMC and bonus tolerance, surface interpretation, patterns, composite FCF's, and optimization.

This new standard will be of great interest to those directly involved with GD&T measurement and reporting such as inspectors, CMM programmers, quality engineers, inspection planners, and metrology software developers. It will also be very useful for those tasked with reviewing GD&T inspection reports and interpreting the information on them - design and manufacturing engineers, purchasers, supplier quality engineers, machinists, and quality managers.

The Y14.45 standard is currently available in PDF format, and the print version is scheduled for Jan 26. Here is a link for ordering:

I've been a member of the Y14.45 development subcommittee from the beginning, and there are other Y14.45 members on this forum as well. We're looking forward to questions and comments!

I missed the public review draft notice. Ah well.

I see it was about 2 years ago.

Evan,
I have a question (since you made this offer): what are the shortcomings of the "as released" Y14.45 standard?
What are those things the committee members could have done it better, in your opinion?
Something that you are not satisfied about the content of this brand new standard?

Thank you and CONGRATULATIONS for your achievement!

greenimi,

Wow, that's a difficult question to answer about something that was just released. We're trying to promote this thing!

I wish that we would have been able to include more examples and figures. These add a lot of value to the document but they are unfortunately very difficult and time-consuming to produce. We tried to make sure that the as-produced geometry in each figure matches the numerical results, and this multiplies the time required.

I would have also liked to include more on the topic of optimization. Specifically, what criteria are used when calculating optimal measured values when there are open degrees of freedom (and thus many "candidate" measured values). We just made a reference to Y14.5.1 Mathematical Definitions but probably could have included a general summary.

Thank you for the update Evan.
This is good news. I was looking forward to it since the draft was published. Are there any significant changes from the draft version?

Burunduk,
I don't recall any major changes after the public review.

 

[greenimi]

Pmarc,
I would address you the same questions as the ones for Evan?
(what are the shortcomings of the "as released" Y14.45 standard)

Thank you very much

I'm more curious about vendor buy-in. Are the CMM makers producing reports in this format and, more important, is the data being accepted by CNC controllers to tune their operations?

I also note that there isn't a callout for expected error bounds on the measurements; it doesn't separate out the fraction of variation due to measurement error.

It does look like a great tutorial for inspectors as to what the characteristic tolerance application means to them, so that's good.

What did ASME contribute to the development of this new standard?

pylfrm,

I'm not sure that I really understand your question. The development is done by a group of volunteers, and ASME mostly acts in an organizational capacity. ASME contributes the following:
-Administers approval of the scope of the standard and subcommittee membership
-Organizes the venue and rooms for the twice yearly in-person meetings
-Provides web portal for committee file sharing and online meetings
-Administers public review and committee balloting for approval of the draft
-Provides editorial assistance and handles page layout once the draft is completed
-Produces final PDF and printed versions of the document

axym,

Thank you for your response. It looks like you interpreted my question roughly as intended despite my lack of explanation.

I'd be interested to learn more about the organization of the in-person meetings. I didn't find much information on www.asme.org or cstools.asme.org about past or future meetings. Does ASME typically just rent some rooms in which to hold the meetings from a commercial provider in some random city?

I think I read somewhere that the meetings in 2021 and maybe 2020 were virtual-only. How well do the virtual meetings work compared to the in-person ones? Has some sort of hybrid approach ever been used in the past or planned for the future?
