Defining GD&T Controls: Form, Orientation, Location, Profile, and Runout | Symbols & Tolerance Zones

This video is pure gold. Explained with the right amount of details to have a good grasp in understanding GD&T symbols and using them. The examples and tips offered during the profile of a surface explanation were very useful. Keep doing the good work. Greetings from Venezuela.

Subscribed. Best material on GD&T ive seen so far. Not to mention, maybe the only one that is useful with great examples and explanations. Thank you very much sir.

I am new learner …❤

Hi sorry but you are not showing all the drawings

Thank you so much for putting this series together. My GD&T background was always rough and after 10 + years, rusty. This course thus far, has been fantastic help in getting me re-cquainted with it. Thank you again!

You were destined to teach because the way you convey information is just pure gold. Thank you.

Two thumbs up!!

Excellent job professor,✌ can I get any PDFs of your GD&T lectures?

why do we need position control is that important to use ?

Your series for GD&T is absolutely fantastic!!

Thank you sir how to reading final inspection drawing

Greate to see the usage of millimeter instead of the horrible inches, greatings from Sweden.

I thank you so much for this invaluable video!

Great job at explaining these concepts! I use GD&T quite a lot at work (metrology), and these videos have helped clarify some specifics for me.

Thanks so much for the awesome series. As someone who's never used GD&T this is exactly what I needed. One thing I'd add to the playlist is the video on the modifiers and examples of when they're used/why.

Thank you so much for these lectures, from someone who graduated in engineering but was never taught this in college

Two points that I want to make:
1. I was waiting for you to go back on unequal profile tolerance zone with the U symbol.
2. It looks like if a surface is flat, you can control it with either flatness or surface profile. Is that correct?

Ohhhh completed the GD &T series I just want to say thank you very very much. Loved your teaching

thank you

Brilliant professor. This video is gold. Thanks a million

do you have solidworks top down assembly design video

if i have a pin on my part, should i tolerance it with a positional or circular runout tolerance? I initially used true position but I just recently found out about the concept of circular runout.

Hi, Some good stuff here but one minor point... ASME Y14.5 2018 no longer has coaxiality (concentricity) or symmetry, instead it just uses position. But it is good to still include it as it's still on plenty of drawings where an older standard is used. Assuming you are using ASME and not ISO!

In your "Milling Machine Vice" example you sort of out yourself as havening not run a mill that much, or at least you are speaking to an audience whom you don't suspect as having much exposure to that machine. So, in the interest of "Constructive" criticism, allow me to offer the following. What you refer too as the "Bed" is actually the table. When a machinist sets up to make a part (that will be held in a mill vice) there are two procedures that he will accomplish. 1) He will bolt the vice to the table and "square" it to the table using a dial indicator. This will establish parallelism between the hard jaw of the vice with the theoretical (usually Y) axis. With that done he will go on to the 2nd procedure. This adjustment will establish perpendicularity between the Z and Y and Z and X planes. This is known as "Traming the head". In this process the machinist will put a dial indicator in the spindle such that it can swing (rotate with the spindle) a full circle reaching all points on the vice slides, then, indicating off of the vice slide, measure first in one axis and then the other (each in 2 places 180deg apart ) and adjust the head (again one axis at a time) to eliminate the difference in the readings front to back then right to left. Last of all, thanks very much for posting this (your) very helpful content.

First of all sir thanks a million for these lectures ,you are illumunating us , I ve been waitng the LMC and MMC lesson eagerly.

Wonderful Lectures ! Thanks.

Thank you very much

Fantastic. Looking forward to the next meeting. Please post when you can!

I've been binge-watching these GD&T lecture series and they are just the best. Awesome content and very well put together. Please also do a video on manufacturing drawings of complex assemblies.
Eagerly waiting for the next part. Thanks a ton!

Please do a lecture on Gd&t application for a complex assembly .and how we should consider datums and symbols to be applied in piece parts and assembly levels.

which control is preferred to use instead of concentricity?

please upload remaining lectures

Great lecture as always.

Upload more lecture of GD&T. Its really useful

Thank you for sharing

Hello, great lecture the same like previous three . What about real example, can you please take one real detail where can be applied all the controls and their mix for better understanding. I am mechanical engineer who has studied by GOST system. Thank you.

awesome again and great explanation !! thanks a lot for sharing

Plz upload more lecture on this subject
