How do you know what value to use for a Projected Tolerance Zone. You stated that it doubles with every plate. Am I correct in thinking that if I have three plates with the same thickness it triples? So, for example the first hole (lowest in the stackup) has a PTOL of +/- .015; then my second plate must have a PTOL of +/- .030, and the third having +/- .060? What if I hade three mating surfaces where one of them was 1.000in and the mioddle one was .675in and the third .375in. Would I then multiply my PTOL by 1.675 and 1.375 respectively? I forgot to mention I am speaking 3X clearance holes through a 3X tsack bolted joint (nut & bolt).

I have a question if you don't mind? A designer at the company where I work has suggested, instead of using basic dimensions, have a callout of position in a feature control frame and a note which states "basic dimensions relating to position are to cad, in line with datum structure". From a metrology standpoint, we can obtain the X Y Z co-ordinates from CAD once the alignment is constructed in line with drawing requirements, and the drawing is defined from CAD... so my question is, is it mandatory for basic dimensions to be called out on a drawing in ASME, or could this method be deployed?

Maybe you’ve never heard this before but I appreciate how slow you talk. That way when it’s a hard concept or one I’m not familiar with I can listen to it at regular speed. To fully understand it and take the information as it’s being presented. And when it’s a concept I’m generally familiar with I can speed it up to 1.25 and 1.5 and it still sounds like regular speech and information is still clear and easy to hear. Thank you for these videos, hard to find consistent videos that go through the topics in a linear fashion while touching on every topic.

In the 1st example, standard way I'd write the CMM program alignment to ABC would be to Level to A, Orient on B, and then rotate or Align to C. It seems to me that by doing this I am 'using' the translation modifier (sideways triangle). Am I missing something?

Not the rather sloppy brazing displayed here. You can also see beautiful stack of dimes brazing on custom bike builders sites where they build bikes of the classic steel frame style.

@RDeanOdell : Just some constructive criticism, you're not wrong in any of your explanations/inspection-set-ups but theres some assumptions being made that are confusing other people. I feel you need to explain the different inspection methods and why you would use that set-up instead of other methods. Explain the need to take into consideration the maximum deviation tolerance and the accuracy/inaccuracies of the instrumentation being used. For example, as for the profile of a surface with a Basic dimension. If the basic dimension is 2" and the profile max deviation is less than .001", I would use a ten-thousandths indicator and a 2" gauge-block to set the height to reduce the instrumentation error and try to be as close to a 10:1 accuracy ratio as possible. Also, temperature is a big factor for high accuracy set-ups as thermal expansion varies from one material to another (aluminum having twice the rate of linear thermal expansion coefficient as steel). I know a lot of shops that dont have a temperature controlled inspection areas. Per ASME Y14.5, all dimensions need to be refenced back to 20°C(68°F). I hope this helps in future videos.

I would like to emphasize that even though the Y14.45 is a new standard, what a metrologist should report is NOT new. If they truly know GD&T, they should know what to report even without this new standard. Unfortunately, the industry is full of people who think they know GD&T but have no idea that they actually do not know GD&T. One very classical example I can give is reporting a feature of size: How many of you know that you have to report 2 values? One for the actual mating envelope and one for the actual local size. Another note is that you can not measure a BASIC dimension, as it is not possible. You have to imagine a very bad part in 3D and try to think what you are really trying to measure to see that. The only +/- dimensions on your drawing should be the features of size, including the general tolerances! +/- general tolerances (length and/or angle) are ambiguous at best.
