Thank you all 3

[Madhu454]

Hi All,
I passed in GDTP-Technologist exam with an overall score of 99%.
I would like to thank all of you for clarifying even my silly questions & helping me to understand the concepts better.

if any one asks me whats is the best book on GD&T , I would suggest this forum. This is more than a book, what is not there in a book and what is not there in standard, that we can find here.

I will start preparing for senior exam soon

Once again thank you all...

Regards
Madhu

Congratulations, Madhu, and good luck on your senior level exam.

Madhu:

Good for you but be prepared for the Senior. Your results would probably be a bit lower as mine were.

You are correct about this forum though. There are many holes or conflicts in the standard. It also doesn't cover all situations. Sometimes we get heated up on a particular subject but in the end, we all learn. I have been training in the subject since 1988 but I have added some of the more controversial topics covered here to my web page.

Good luck on your Senior but you will be brain dead when you complete the exam. Hope you find your way home after.

Nicely done. Remember to use the linked-topic method when studying for the senior level, and work at it diligently; it is a significantly larger and more in-depth body of knowledge.

What do you mean by the linked-topic method Jim?

When you get a copy of Y14.5.1, you start with the first item in the Body of Knowledge (BOK). When you go to that first section, as you read it you follow every link that it directs you to (paragraph or graphic) and study that sub-topic and each of its branched sub-sub-topics, and so on. When you are done the sub-topic, you go back up your chain and follow the next sub-topic branch, and repeat the process until each linked sub-topic is exhausted for that parent-level topic. Then you go on to the next parent-level topic from the BOK, and repeat the process. In this way, you end up studying most paragraphs in Y14.5 several times, and most graphics even more frequently. I suggest putting a checkmark or such next to each paragraph & graphic (and sometimes sub-graphic) in your copy of Y14.5 each time you study that component. You may also want to record each of the topic branches as you go so that you can follow your way back up the tree and take other sub-branches, without getting lost.
By the time that you have gone thru the entire BOK, you will find that you have studied most sections at least a couple times, and the more critical sections and graphics almost a dozen times. This method of study also gets you to the point where some of the more subtle links of topics become fairly intuitive.

I just didn't want him to start reading about mathematical algorithms of tolerancing and dot-products and matrices and .... snore....

I have heard that, senior level exam will contain more questions on resolving the 'tolerance stackup Analysis for individual and assembly parts' is that true?

Hi Belanger,
I did not get what is "mathematical algorithms" & "dot-products and matrices"

 

[Belanger]

I was just joking -- the 14.5.1 standard is "Mathematical Definition of Dimensioning and Tolerancing Principles," and it gets into some of the tedious math about GD&T. It might be some folks' cup of tea, but my eyes glaze over when I spend more than 5 or 10 minutes in that book. Nothing in that book would be on your test.

Jim was referring to 14.5.2, which is the short standard that lists the "body of knowledge" which you'll need to know.

I don't think the senior level exam gets into stack analysis as you describe (other than things like virtual condition). Instead, it has more of a focus on the proper application of GD&T, plus of course harder questions in general. And also composition position vs. 2 single-segments. The best answer is to look at 14.5.2.

per JP, TSUs aren't part of the exam as they aren't part of the standard; they're an offshoot of the standard.

Get a copy of Y14.5.....2 (got it right this time, JP).

Oh, by the way, JP ... some people have said the same thing about reading Y14.5, reading patents ... all the fun stuff that some of do recreationally ;~}
