ASME Y14.100 and ASME Y14.35M
ASME Y14.100 and ASME Y14.35M
(OP)
Two questions for everyone-
1- How many of you are actually adhering to these standards? Please also mention if your organization is within an order of magnitude or so of $65M/yr and approx. 300 employees. (I have a theory that adherance to these standards is proportional to the size of the organization.)
2- If you are in compliance, to what extent did you "grandfather in" existing drawings at the time of implementation? Also did you grandfather in your old drawings in perpetuity or only until the next revision? Clause 4 in Y14.35 requires that you must add the 'IAW ASME Y14.5' statement at the time of revision but I can find no other instructions in the standards.
I will appreciate the help folks!

My current job, we do it all, plus more. MUCH bigger company.

I am working on changing that though and I just got done writing a company standard that follows Y14.35 and Y14.100 pretty close. I can't say that we will be following it to the letter but we are close.

I think their are a lot more variables that control/affect adherance to many standards. Our company is $40M/160 employees and we follow the standards about 65% of the time. We have a lot of trible knowledge and people that have been here a long time.....those are the two hardest elements to change. I here this all the time when I'm trying to institute change "we have being doing it this way for 30 years". My response well now you're doing it wrong and here is how you should be doing things.

Within four months, we set up and established ANSI/ASME standards to Y14.100, Y14.35, and Y14.5M, and ran training classes on GD&T.
We set up a policy that all NEW designs will meet the new standards, and all redesigns to solve design problems will go through DFMA and GD&T analysis and reworked/redesigned components and their related parts will use GD&T and new formats IAW Y14.100/Y14.35.
As of today, the designers of one product line (who work for the aformentioned visionary manager) comply, and the rest of engineering (~55%)only comes to us when a design is in trouble, or serious manufacturing problems arise.
From our experience I think both company size and product complexity and maturity eventually force compliance with industry standards.
It is still a battle, since the "old Guard" of the company assume we are trying to force military style standards on free thinking commercial engineers, but corporate has seen the positive results of our efforts in improving the product, and realizes that there are cost savings to be gained by our efforts, although they are often hard to define or document.

Congrat's to you and your company for moving forward.
I tried the same at my last company. The biggest hurdle is keeping purchasing and marketing out of the process.

There are a lot of people still fighting the AutoCAD switch to solid modeling, lots of bad habits to break. Then there are the green CAD users that still need to be trained in why a certain component should be modeled in a certain way. I doubt I'll see any compliance with Y14.41 within the next 3-5yrs.

1. Our site which is the only one we’ve had any impact in so far has around the number of employees you mention. However if I recall its turnover is much higher. We don’t yet across the board follow the standards, however the 5 of us in our group and our interns try.
2. For the most part our group try and grandfather in old drawings when we work on them for revision. We always put them on new formats to the standard, tidy up dimensioning, incorporate GD&T where possible, reword notes to be requirements not instructions etc. We tend to be a bit more lenient on what we let pass on revisions though, especially when to change it causes a lot of work. We’ve gone through and revised a few packs primarily just to bring them up to standard but usually it’s things that needed revisions for another reason. Others outside of our group don’t tend to bring old drawings up to standard though.
Ctopher, we just submitted our design room manual for approval and we’re not a large aerospace place. We used it primarily to emphasize certain areas of the standards that we feel are particularly relevant and to clarify things in a few places where the standards leave it a bit open (replaced a few ‘shoulds’ with ‘shalls’ etc). We also included stuff on how to use our CAD system to meet the standards etc and best known practices for model and drawing creation using our CAD system.
As Ron mentioned we’re being questioned again, I just put this in an email titled ‘In defense of industry design standards’.
I then went on to address a couple of contentious items in detail.

With your permission I would like to quote your quote and show it to some folks here. Please let me know if that is ok with you.

I was fairly sure that would be your answer, but to reverse the old adage, I prefer to ask permission, not forgiveness.

We don’t grandfather in old drawings in my group, we normally try to bring them up to standard as I put in the rest of my post.
John you're making me feel bad. I use info from this site, though not usually direct quotes, a lot without asking permission. So I guess a big thank you to everyone I've plagiarized
