Thank you so much Dean, I've learned so much watching your videos that has cleared so many doubts I have had working with GD&T over the past 5 years into my career

For an assembly like this (a machinists tool) I don't think you would want to make the holes a datum for a reason I didn't hear you mention. Chiefly because threads are typically imprecise and hard to inspect.

Thank you, it's a little clearer now but this is still the hardest part for me. Could you perhaps show us a complex geometry part? Something with organic and horz/vertal geometry?

I never would use the introduced datums B and C for a functional based specification: There are no contacts at B and C! … only air.

Great explanation. Can you please explain what would be the interpretation of those A, B & C in circle next to feature frame and the numbers 1,3 shown in the triangle..

Thanks! The circles are revision symbols, the triangles are flag notes that refer to the general notes on the drawing. The complete drawing is available at the link in the description.

Can sb explain, why at 5:05 base dimensions for hole positions are based to rounded profile on left side (which is not a datum), instead of being based to datum C?

The 3 datum targets of the first datum, resulting in the 3 points forming a surface at an angle to the coordinate plane. Question: Is there any negative effect of if the first datum plane is not being parallel to the coordinate axis at too large an angle?

It can be indicated with the “U” symbol in the FCF, or with a phantom line near the part outline on older drawings.

I’m not certified, but my understanding is that the test is based very much on the verbatim wording of the Y14.5 standard. I recommend reading the standard cover to cover, and then have someone quiz you on particulars.

@@RDeanOdell I'm learning ASME Y14.5 2009 from ASE and it's torture. I'm a CNC programmer/manufacturing tech and have a background in CMM programming and I found the tests to be infuriating because they're based on the wording and not the practical applications of the rules.

And this is why the US can't compete with Asian manufacturing. I've studied GD&T almost since its inception. I know it extremely well. Requirements are placed on components that significantly increase manufacturing cost without providing any benefit to the customer. Now I'll sit back and let the GD&T experts tell me I'm wrong. I'll sit back and watch the western manufacturing market continue to decline while Asian market destroys them.

Hi, great feedback! I won’t tell you you are wrong. I believe the problem is that designers and management are overly conservative in design requirements because of a lack emphasis in the design process in general, of which GD&T is just a portion. In most of my explanations I use two decimals places and .04 of tolerance. I think many textbooks influence designers in a negative way by using 3-4 decimal places and restrictive geometric controls in many examples. In my opinion GD&T is a way to get design, manufacturing and inspection on the same page, and is not limited to critical high performance items with tight tolerances. Is there something else I should be teaching my students that would help us compete with Asian manufacturing?
