GD&T reference book
(OP)
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

RE: GD&T reference book
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!

If ASME though, there is also a quite comprehensive and easy to read book by P. Drake "Dimensioning and Tolerancing Handbook".
RE: GD&T reference book
For the beginner in ISO I would recommend Krulikowski as well:

RE: GD&T reference book
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")
RE: GD&T reference book
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.
RE: GD&T reference book
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.

RE: GD&T reference book
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!

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.
RE: GD&T reference book
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

"Geometric Dimensioning and Tolerancing for Mechanical Design"
by Gene R. Cogorno
A self-teaching guide to the ASME y14.5M-1994 standard
RE: GD&T reference book
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?

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

RE: GD&T reference book
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.
What is Engineering anyway: FAQ1088-1484: In layman terms, what is "engineering"?
RE: GD&T reference 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.

RE: GD&T reference book
I looks like ISO realized that Alex Krulikowsky beat them, so together with Danish Standards (DS – ISO member for the country) they have jointly published a handbook on geometrical product specifications (GPS). Here is the link:
htt
The book is authored by Dr. Henrik S. Nielsen, Chair of ISO technical committee ISO/TC 213, which develops GPS standards with the participation of ISO national member bodies in 23 countries.
Right now you can buy it directly from the ISO Central Secretariat, price 70 Swiss francs, but eventually it should be available from places like ANSI or ASME web stores.
For anybody interested in ISO standards the publication info for easy search is as follows:
The ISO Geometrical Product Specifications – Find your way in GPS (378 pages, B5 format, English only, ISBN 978-87-7310-721-8)
Disclaimer: I do not work in ISO, ASME or ANSI store.
RE: GD&T reference book
Thanks, I think it looks real good. I need to understand this whole GPS philosophy; I see it constantly in searching for ISO standards. I notice that is the topic of the first chapter. I appreciate your catching this for me.

RE: GD&T reference book
By the way i have ordered for the TECEASE book (GD&T HIERARCHY TEXT).I used to watch TECEASE videos on youtube and thought the book will be worth starting with.
Thanks again all of you.

RE: GD&T reference book
On Henzold, I had a book of his a while back; it was his work on ASME GD&T. There were a number of issues with it because he used ISO interpretations where they were inappropriate. Just a caution for anyone considering his materials. I know that he is extremely well respected within the ISO community for his work in that system. What I heard was that he was making inroads into the ASME domain because sales of Y14.5 outnumbered DIN & ISO in Europe for a period not that long ago. Seems like neither side of the pond is completely satisfied with either standard.
