Y14.5 Books?

Perhaps if you explained what Y14.5 is...although presumably, if I have to ask that, then I can't help you with your question

Rose, it is the ANSI standard for the Geometric Dimensioning and Tolerancing of drawings to allow for proper fits at assembly. It's really a language to allow the person making a part to make it as intended by engineering, and assure parts made in different locations will fit together properly when mated.

Bill :-)

Ah. See if you'd mentioned the BS (British Standard) number, I might have recognised that!

Try your local technical colleges and universities. I bought my students' edition in my first year (too long ago!)

I'm guessing you're in the States, so I don't know if you have an equivalent of the TSO (pls google, I'm late for a meeting!) who may supply such stuff.

Rose, I'm not aware of a BS standard but there is an ISO standard (ISO 1101) that is about 99% the same as the ANSI/ASME Y14.5-1998 standard. The differences between the two are down in the weeds.

I think the BS Standard no is BS 8888

Hi Bill,

I'd say use the spec itself, not someone else's interpretation of the spec. I've seen too many people (engineers) who took someone else's text book to heart and got it wrong. I have examples, where I work, someone grabbed a text book interpretation of the spec and then put TOTAL RUNOUT (double arrows) callouts on all our prints. We can't inspect TOTAL RUNOUT but we can inspect RUNOUT (single arrow).

I took a college course in the spec back in the '80's and after that I refused to use any text book, even when I taught it at a course for our engineers years ago. I always keep a copy of the spec near by.

today I have a copy within arms reach.

I would strongly recommend Geo-Metrics III written by Lowell W. Foster, who was one of the original architects of the standard. He was a tooling engineer for Honeywell before he was tapped by ASME to help write the standard. I attended a 3 day seminar presented by Dr. Foster and he is very good at explaining both the usage of, and the thinking behind the standard.

you can go to www.constructarea.org there have Y14.5-2009,just need 29$,there also have many cheap ASME AWS,ASTM,API standard PDF can download!
