Tolerance Stackup: Vector Method with GD&T
Ғылым және технология
I calculate a gap with an assembly of two parts that are shifted.
The parts contain GD&T, and I show how to calculate vectors.
I also compare a boundary analysis to a vector analysis.

Thanks so much!
Thank you very much Shawn Michaels..
Thank you Sir. I can see a little better in the muddy waters now. =o)
Great video, thank you!

Glad you liked it! Thanks!
I like your explanation but one point of confusion is the sign convention at 8:00 when referencing the vector directions. Your vectors are drawn bi-directional, so, when you say right-to-left you are pointing to a vector that has two arrows on the board. Can you clarify this with tip-to-tail vectors, i.e. point at the start, line, and arrow at the end?
Hi this is really helpful. However please make similar video for a set of or pattern of holes and pins mating with each other. That gives a lot more clarity for real life applications we do at our work. Thanks again.
Thank you👍

Dear Sir, a question I need clarity regarding measurement of Flatness. A component ( a connecting rod) has been given flatness on one of it's face. Can this flatness (0.05 mm Or 50 micron) be measure by resting the component ( on its side where the flatness is called on) on a surface plate and then using an filler / feeler gauge of dimension 50 micron (as go gauge) and slide it between the part and the surface plate to ensure its within limit and then a 51 micron ( as a no gauge) feeler gauge to ensure its not exceeding 50 micron?

Hi, using a feeler gage is acceptable in some cases. It depends on the geometry of your part. Can the feeler access the entire surface? A feeler gage can also not be trusted in all cases because it will not pick up on surface cavities. A visual inspection may be enough to eliminate the surface cavity problem.
Nice video' can you please make video on some other example of tol stack up... Tq again
Dear Dean Thank you so much for your information :) I'm just curious what is haft vector formula came from? Can you please explain more in these formula. Big thank
Thanks for the video @Dean. If the datum is assigned to the feature of size and the datum is modified with mmb in feature control frame, will the datum shift need to be factored in this calculation. Please clarify.

Hi, In this example the datum scheme would need to be changed for MMB to be applicable. If the hole was a datum feature at MMB, the shift would need to accounted for in the gap analysis.
Thank you

Hi Dean. Great explanation. Here we are using vector methods for positional tolerance. 1.Can we use the same vector method concept for remaining GD&T symbols to convert them to ± tolerance? 2. How to do the same stack up in two column method without using vector concept?
how do we shift from one part to another part for vector loop, Thanks for your teachings...!

Hi, to move from one part to another, there must be a point of contact so that the dimensions can loop.
Hello Sr. Odell . i got lost on 10:20 both FOS have Maximal Material Condition why are we using the IB (LMC) and not IB (MMC)?
Hi, a question for you, Im trying to figure out where you got the half vector formula from? Thanks

Why are they called half vectors instead of average radial factors? Half vector seems confusing and not descriptive.
I will check in creo...lets see
