You're an excellent teacher, I'm grateful that you share these lectures. They helped me immensely during my studies as a mechanical engineering student.
Thank you! It makes me feel good that I might be helping some people. All the best to you in your career!
I moved to Louisiana (from Virginia) back in 2012-2014. Loved the state, met a couple of La Tech engineers. Top notch people.
Glad to know our grads are representing us well! All the best to you!
I've seen lots of your videos, and it help me a lot in my mechanical design engineer career. Many thanks
I'm glad I could be helpful! Thanks for your support!
Thank you so much for this. I have been looking for someone who has a throw and detailed explanation. Just this video alone puts you at the top of my recommendation list on this topic
Hello Dr. Swanbom, I have been watching your videos for 3 days now and I can't say enough how your lectures are helping me brush over my concepts from years ago.
Thank you for putting online these intelligent and crystal clear lectures. It’s obvious that you have a very good grasp of the topics that you teach, but what’s even better is your ability to communicate that understanding in such a concise and that-makes-sense manner.
I'm honored by your kind words! Thanks for watching!
Really liked the way you combine all important concepts into a video! You videos are treasure for mechanical engineers!
I am following all your lectures !
Over the years, I've studied numerous video compilations devoted to GD&T but always gravitate back to the TheBom_PE series. Anyone interested in learning GD&T from scratch should watch this video series in order and read Chapter 20 on GD&T in Shigley's Mechanical Engineering Design. I cannot think of a more thorough and comprehensive starting point.
Finally!! Thanks for explaining this in layman's terms.
I'm glad it was helpful! Thanks for the feedback! Here are some of my other playlists in case you haven't seen them yet and might be interested:

Thanks for watching!
I'm sooo grateful for the way you've carefully helped me to link imperfection, achievability, functionality, cost effectiveness and other ideas linked to tolerance selection.
I'm glad I could help! Thanks for watching!
Professor Aaron Rodgers does it again! Absolutely nailed it. Thanks for being this awesome and sharing it freely with the world. You are the MVP of professors. Greetings from Brazil!
Greetings Brazil! I don't know what to say, but thank you! I'm glad you liked it!
Thankyou for sharing your knowledge and experiences. You have imparted well on his subject. All those who share openly in TH-cam are for the benefit for mankind is indeed a blessing. Many readers would benefit from your other lectures as well.
I'm glad they seem to be helping people. Thanks for your encouragement!
You're the best, these videos are very educational. This is helping a lot. It would be really cool if you did a lab day and measured parts and went over the gauges and tools used in metrology. Or even some CMM stuff.
i CAN'T THANK YOU ENOUGH ..... I REALLY APPRECIATE YOUR LECTURE !!

This is helpful as a refresher for us that have been out in the world for a while. Thank you sir
Hello Professor, I just wanted to let you know how much I appreciate you uploading these lectures on GD & T. I have been searching for informative GD & T videos for several months now, but non of them are as detailed and well explained as your's. There are a lot of books to learn from but what I feel is when it comes to GD & T, it's best to learn from a professional and I'm really happy that I found you on TH-cam and that I can finally learn GD & T. Looking forward for all your lectures related to it. Thank you so much!
I'm glad you enjoy the GD&T content, thanks for the positive feedback! I hope the series at least provides a reasonably good foundation to work from! Here are some of my other playlists in case you haven't seen them yet and might be interested:

When are the new videos coming in? These are excellent!
Thanks! I do have some more in the works, they just got put on the back burner as I try to make classes suck as little as possible in the age of COVID. I hope to put some videos out in the near future.
Hello Sir..can you please explain what will be the effect if we interchange hole size tolerance with its position tolerance
thank u sir give good training
Glad you liked it! Thanks for watching!
This really takes practice and time to learn

That's the beauty of engineering! I'm taking a Cad Design class here in California leaning towards mechanical engineering I have my midterm at 7 pm due to coronavirus. Stay safe!
Will be taking mechanics and lab this fall so I subscribed :)
You stay safe too!
Good deal! Good luck!
Great teacher
You are very kind! All the best to you!
Awesome video, I am struggling to understand the differences between tolerance, allowance, and fit.
thanks a million Professor, which textbook are you using? thanks again!
Thanks sir
Glad you liked it!
太好了。
Thanks
Thank YOU!
hi...are you going to upload complete lectures for meen 426 in future?
What a lecture, you're amazing. By the way out of curiosity, Is the default playback a little sped up? Just asking for my own sanity haha.
Nice catch! Yes, I did nudge the speed up just a little tiny bit so that I could fit the whole thing into a 75 minute timeframe. I use this video as one element of a course I teach here at Louisiana Tech University, and the regular class periods are 75 minutes long. To help avoid criticism about having a lecture that was too long, I just made a little edit :)
@@TheBomPE that's smart! You also saved days worth of time I suppose 😅 since 75k viewers watched your video.
I may have missed it but what text book are you using for this class?
You did miss it, it's on the first slide! ha ha. Good ol' Shigley!
@@TheBomPE Okay lol I figured it was Shigley just wanted to make sure. Definitely gotten some mileage out of that book!
muy bueno
Gracias!
Is it ISO, the standard that you use? what is the number of this ISO standard?
No, I'm not using ISO for this series, although I might mention it here or there if it is relevant. I'm focusing more on ASME Y14.5, but truthfully I'm mostly interested in the big concepts, not quite as much with the really fine points of any particular standard.
Really cool. What textbook did you assign your class?
We use the 20th chapter in Shigley's Mechanical Engineering Design, 10th edition. There are definitely more complete treatments of GD&T than this source, but at Louisiana Tech University the ME students all have this text already from two previous courses. It's a good backbone for a 1 credit course, supplemented with other sources I collect (like the ASME standard itself). Thanks for watching!
what is the reference book for your teaching sir ?
I'm teaching out of Shigley's Mechanical Engineering Design, 10th edition. It is just a 1 credit introductory course.
@@TheBomPE How many lectures do you plan for this course? I hope it'll be more detailed lectures
@@TheBomPE How many lectures do you plan for this course? I hope it'll be more detailed lectures
Right now I have about 8 lectures planned, where I will deliver about one each week. I will get into more detail on individual topics as it progresses. The next one will be about Datums, reference frames, and actual mating envelopes.
@@TheBomPE Great job professor, you are the man,, I hope you will explain tolerance stack up too.
A few things were not clear in your lecture though, e.g Run-out.
Some of it I got
Some of it I didn’t get
A completely & utterly confusing discussion about how poorly stuff was historically made in Wisconsin. I turned it off a 1/3 of the way through.
I'm sorry this material is confusing for you. Perhaps engineering isn't your thing, and that's OK. There are videos on other TH-cam channels that teach things like colors, shapes, and animal names. I recommend looking into those. Best of luck in your educational journey!
@@TheBomPE I work in the engineering department of an aerospace company. The video was supposed to be about GD&T, not the history of tubing and all the arcane screwed up ways they've use to size it. In Aerospace they call out wall thickness and ID or OD diameter in mm or inches. How would GD&T apply to that? Or maybe teaching isn't your thing?
Perhaps there is some aerospace engineering work that needs your input more desperately than TH-cam needs it. But I could very well be wrong about that... maybe throwing stones at a freely-offered video that many have found helpful is the most important contribution you have to offer. I do apologize for mistaking your age earlier. I shouldn't have just assumed based on the nature of your comment. I wish you well!
Too basic , too academic.
I'm sorry it wasn't what you were looking for! Would it be better if a series of talks on more GD&T details followed?
9:30 -> need correction -> Τol. ±0.01 in ~ ±0.25 mm not ±0.5 mm...
Thank for that video!
