The best for gd&t ! Thanks

Mind blowing explanation...

Fantastic way to describe Datum Shift, thanks!

For manufacturing and inspection professionals, it is a big bonus if you understand the design intent/application. Good job for explaining the design intent and requirements.

Great explanation! Thank you!

Can you explain further how’s Datum shift used . I understand it’s not bonus tolerance but next lesson please explain how to use and when to use . Thank you

Very good example. Thank you.

That was really simple and easy to understand. I am very thankful to you for this video.😃

Hey Quint , your methodology of teaching is very unique I have seen a bunch of GD&T courses they either copy paste from ASME Book or just go on with very conventional style but yours is truly awesome with "NO MATH", easy to understand, easy to learn and easy to relate. I have a request if you can make videos on calculating some of those terms like positional tolerance, bonus tolerance and datum shift/ diametral shift including some math/formula. It would be great since those are the most used also important in GD&T and manufacturing. Thanks !!

Great use of a DATUM SHIFT concept applied to GD&T. Thank You! Thomas J Vanderloop, CMfgE, Author, Technology-Instructor & Industry Consultant; AWS & LSME-Leadership

Excellent excellent you did a great lesson for us Thank you very much

Awesome explanation

Man you are awesome ❤

Great vid. Thx

It could be more helpful if you could go little more about inspecting “Datum Shift” bonus. Thanks for the video. It’s fantastic!

The example used in the video to illustrate datum shift and bonus tolerance was excellent. I understand that while learning the language of GD&T, it is important to be exposed to as many different ways of doing things as possible so that it will be in the GD&T users tool chest. But, how would you simplify the datum shift and bonus tolerance FCF where 80% of GD&T users would understand without calling in an expert?

Great videos, please ,ake one about stack-ups!

Nicely explained but can u help to understand how the datum shift will help in manufacturing of part.

Thxxxxx

Your videos are fantastic. Thankyou! Probably doesn't affect the point of the lesson, but isn't the smallest size of paper one where 2 punches are right on the edge? (so a little smaller than was used in your example?)

loving the vids so far. thank you. gotta min? I took some machining classes, applied at a place to be a machinist. I wore a coat & tie to the interview, the Director of Quality saw me & told HR to put me in Quality. That was 5 years ago & I am now training to be a QT directly to QE (i'm already designated QE on projects). I am struggling with a few things (mostly paperwork related... ie pFMEAs, PPAP, etc... i'm getting that sorted though). I would fancy my GD&T higher level (as compared to most people in this company) but struggle with a few things. Can you point me in the direction of how I can grasp... 1 - tolerancing to a profile. As in the tolerance in the title block has profile of a surface w/in .005 & un-toleranced dimensions are "basic". I assume then for inspection purposes - ±.025 2 - i have a basic distance dimension that the customer wants 100% inspected, but they don't want the profile that references it inspected outside of an FAI. What tolerance can I apply to it? the tol on the profile is .062 - so i would assume .031 I am arguing we need a custom gauge to locate positions & profile as this particular part is too large to fit on a vision system or OC & our CMM programmer can't get reliable hits on very small radii. The gauge will get the distance quickly as well as verify the rest of the features. 3 - manually calculating position, or 2-D position (x,y) on a CMM when there is 3 datums. obviously 3 datums will determine fixturing & programming... but for inspection purposes? I argue that position in xy is position. the reference to perpendicularity isn't part of the position formula & should be measured separately. therefore plug deviations of x/y into the formula to get position. the MEs say only a CMM will work - yet the CMM programmer doesn't construct a cylinder.... just a circle.... effectively making it 2 dimensional in my eyes. I don't see how that is any different than using an OC or EHG to establish deltas in x/y. As a matter of fact I would argue that it would be more accurate to take an x/y position open plate from both sides of a bore & that would be more accurate than the current CMM protocol.

Can you explain further how Datum Shift is used? How much shift we can use? The half of the Hole Deviation for each direction? Thank you!

Hi please explain datum shift again...in detail manner.....with more examples

🙏

Can i use this course for my personal use,, if you dont have copy right

Do you have Patreon account set up yet? I would not mind at all to support you on per-video payment basis, as this is great reference material with explanations clear enough even for the production guys. More in depth topics oriented on the engineering side would be greatly appreciated too (tolerances stackups, preventing overconstraints, DFM, etc).

@Deacon Warren Happy to help :D

Great explanation with a the support of this sheets, binder and puncher. I only was thinking about your comment on punching one hole first and the other two. The machine (the puncher) is actually not capable to do that, it can only punch the three wholes as a linear pattern at the same time every time. And actually many machines in the industry are working the same. If the woles can move only as a pattern and the jaws on the puncher are completely wide open (at their Least Material Boundary) wouldn't then this condition be considered as a bonus tolerance? I understand bonus and datum shift are different concepts, but isn't datum shift also giving space for variations when the position controlled features move around together as a pattern? Thanks a lot again for the video. I found it very illustrative =)

Next lecture?

Confused

Great vid. Thx
