ANSI/ASME standard

ANSI/ASME standard

ANSI/ASME standard

(OP)
Hi,

I need ANSI/ASME Y14.5M-1994 standard (Geometric Dimensioning and Tolerancing). Does anybody have any links to WEB to find it (not to buy )? Or maybe somebody have it in electronic version (.pdf files?)?

I will very appreciate your help.

RE: ANSI/ASME standard

Good luck!  That standard is not in the public domain, but is maintained by ASME, who expect to be paid for their efforts.

RE: ANSI/ASME standard

If you need it you can buy it by going
to the web and see if anyone wants to
sell it for a reasonable price as a
used book.  It is an invaluable tool to
use to understand geometric tolerancing.
I think technical libraries may have a
copy available to loan.

RE: ANSI/ASME standard

Most of those kinds of standards are not available as free downloads (unless someone chooses to violate a copyright as a favor to you).  But you can download them for a fee, and often it is worth the fee just to answer whatever questions or uncertainties exist.

RE: ANSI/ASME standard

My company's subscription to a standards service provides all of the standards in downloadable format. Of course we agree with all applicable copyright laws. If you are a  serious designer/engineer and work for a company, pay for the spec. It's one of the costs of doing business and well worth the money.

I've worked with the standard for many years and have found that it is VERY helpful to get a textbook on the subject;  the standard is very terse and formal and simply doesn't provide sufficient depth or examples.  I can recommend two good textbooks on the subject.  Just say the word.

Our company uses the Drafting Zone - http://www.draftingzone.com.

The documents are based on quite a few standards, including the ASME Y14 series, and the web subscription is rather inexpensive.

If you need the actual standard, you can buy a download on the ASME website - http://www.asme.org.

Tunalover,

I just want to say the word ! What textbooks do you use?

Thanks in advance!

RE: ANSI/ASME standard

Apologies if this is OT but, within ANSI Y14.5 94, 83, 73, etc standards, where does it say (section, paragraph, page, etc.) that the drafter is not permitted to mix fraction dimensions with decimal dimensions while using  the "inch" system? or that it is a major faux pas to do so?
The general tolerance block in the border, in this case, has both fraction based tolerance and decimal based (xx, xxx) tolerances listed.
 
Thanks,
CCW

The website manager apparently removed my reply to you because I included my work email address.  Please contact me through the regular forum channels...there's a way.

I'd be happy to provide you with the titles and ISBNs (as I said in my reply) but you need to somehow provide me with your email address.

ccw, try posting your question in a more suitable forum: Forum1103

Check the university library.

RE: ANSI/ASME standard

The 26th edition Machinery's Handbook has some cryptic information about geometric dimensioning.

RE: ANSI/ASME standard

Geometrics III is a good reference to GD&T. It is written by one of the authors of the ASME standard.

In answer to the question concerning the mixed use of fractions and decimals on the same drawing. I am unaware of any ANSI standard that prohibits thier mixed use as long as there is specific tolerances applied to each in the tolerance block. There may be an internal requirement to your company. And if you want to continue working there you may want to comply with that internal standard or at least try to get it changed first through proper channels. ANSI/ASME Y14.5M is not law, it is a guideline. Companies comply with the guideline as they see fit. Bucking company policy is often a surefire way to become unemployed.
