Hi All,
I need a good reference book on geometric dimensioning and tolerancing.As per my discussion with some of my collegues i listed some recommended books.One by Alex Krulikowski ,Second by Bruce Wilson and third by James meadows and fourth by David Madsen.Could anyone help me figure out which one is the best of them all.I am a beginner in this domain :)
Regards

No book is perfect.
Depending on your line of work you may need more than one and eventually end up buying actual standard books as well.
A. Krulikowski's "Essentials" is very thorough, may be a little dry for the beginner; unfortunately "Advanced" was not re-printed for really long time.
J. Meadows is author of several books on GD&T and CMM; I would say it's advanced reading for after you figure out the basics.
I never had a chance to see a book by B. Wilson, and for some reason was not very impressed by D. Madsen; but this is only my own personal opinion.
As standards went thru several changes during 2008-2010 period, most books on the market are falling behind the latest revisions. If you are in charge of using "latest and greatest" standards, you or your company will still have to buy actual standard books.
Good luck!

Good question, Frank.
If ASME though, there is also a quite comprehensive and easy to read book by P. Drake "Dimensioning and Tolerancing Handbook".

CH,
You would recommend the Krulikowski book, I am impressed? I am afraid to spend money on ISO books written by US people, just judging on the attitudes I see here and elsewhere, do you think it is really intend for ISO training, or, traing about ISO?

It isn't perfect, but definitely step in right direction; an honest attempt to cover all the bases. With all its flaws looks like good book for beginners (I was surprised myself)

For advanced ISO reading I would chose autors who spent more time in ISO enviroment like Georg Henzold (search Amazon), and for relatively inexpensive desktop referense books by Paul Green (different editions available. The look and feel of Greens book is somehow similar to Krulikowski "Fundamentals")

I haven't had a chance of reviewing Alex's ISO-based book so far, but I heard some very good opinions about it.
However if I were him, I would be really furious to see significant and important updates of some fundamental ISO GD&T/GPS standards (8015:2011, 5459:2011) coming up right after my book was published.
I guess this is the main reason why there are so few ISO-based books - years of author's work and the book can become out of date just after few months of existence.
Henzold's book is a perfect example of how 'extension of principles' philosophy works. A vast majority of figures in it is not shown in any of ISO GD&T standards - they are based on author's experience and interpretation of general rules.

Hi Experts...Thanks all of you,
My job profile doesn't necessiates me to learn GD&T but i would love to learn it for myself.I know basic terminologies of GD&T but feel untill and unless i apply the same it is not going to be of any use for me.I will remain hooked to this forum.Perhaps that will help me chalk out a way i can learn and use GD&T.Thanks all of you again.

CH,
Thanks, I have both of those books and had been avoiding the one you named for the reasons I gave, above. I really like Georg Henzold’s book. I do want depth, no fluff the other book is more just the basics. Please let me know if you find others like Henzold.
I am tired of ASME spin on ISO, I want to learn from people who have to live it day to day not give it up after the class. I think you are one of those people. pmarc does seem pretty good too. I will make my own decision on which way is better.
I have made my determination that ASME has made some errors and I am NOT willing to surrender the concept of concentricity to the runout crowd. The new ISO release gave them a chance to “change their evil ways”, I suspect they have some of the same concerns I do.
ASME has flushed GD&T out better, true and we can be grateful for that, but, they are also beholden to concepts that are no good. A flushed out combined ISO standard will be better for all in the LONG run. In 1982 they said that would happen next time, I think they may be farther apart now. We should not have made our drawing look like theirs but not the same, however that came about was just wrong!

Sorry, let me try this again, ASME should not have made our datums look like theirs, while not also accepting the same concepts. I do not know the politics behind that decision but it was just bad, To confuse people to make something looks the same, so typical for our consumer culture, but not to also in fact be, that is fundamentally dishonest.

kapmnit123,

If ASME, make sure you have a copy of ASME Y14.5-2009.

You might as well go straight to the source. It is quite readable.

JHG,
I agree that it is a pretty good place to start.

I like Wilson's, Has Lowell Foster done an update, his were good too. Frank

Another easy book, very good for beginners, in my opinion is:

"Geometric Dimensioning and Tolerancing for Mechanical Design"
by Gene R. Cogorno

A self-teaching guide to the ASME y14.5M-1994 standard

Pmarc,
The ISO standards are so basic in presentation any book with good depth is going to be an extension of principles. Henzold is a member of the ISO standard committee as I understand, right?

That is exactly what I want more books about ISO tolerancing from people who use it, live with it daily, and succeed in making it work. I get plenty of “there is no way they can do this like this’. It is hard to believe they have survived as industrialized countries ;)
In English.

Given that the most cited reference on this forum is Tec-Ease's Tips, I would suggest considering their book as well. It's written to be learned by examples as opposed to learning theorems. Many reference books are decent from a technical perspective, but their style and means of communication make them dry and difficult to follow. Tec-Ease uses 3-D colour graphics and lots of different scenarios in their examples. Suggest the 2009 version over the '94 version as it includes the content of both and illustrates the differences.
And no, I don't get a commision.

Jim,
Tec-Ease has a book? I was not aware of that.

I'll back up drawoh and say start with the source (relevant version of ASME std in this case) and go from there.

A book may well help with this but from what I've seen they (like trainers etc.) can tend to have their own biases etc. so having the actual standard to reference is in my opinion indispensable.

Posting guidelines faq731-376 (probably not aimed specifically at you)
What is Engineering anyway: faq1088-1484​

Yup, Frank. It's the Fundamentals training manual. They self-publish to keep the costs down, so it's only thru their site. It is ISBN listed. It's ridiculously expensive to go thru a mainstream publisher, especially with the amount of colour graphics used in the Tec-Ease material. Also allows them to upgrade the content to reflect recurring questions and inputs more frequently, making it more current than most other publications. The full-colour pocket-guide follows the book (essentially has the full content of the book).

As for the actual ASME Y14.5 standard ... not a big fan for somebody starting out. Far too few examples to be practical, and without more real-world examples, it's hard to learn. That being said, it is a necessity when you get serious about doing good/proper GD&T.
