I genuinely, no joke, don't think I could do Mechanical Engineering at university if it wasn't for this channel and I just want to thank you for everything you've done and everything you continue to do. You will never understand how appreciated you are and I have told and will continue to tell fellow engineering students how awesome and fun you can make engineering to learn compared to the lecturers I'm stuck with. Thank you so much.

    This is, without a doubt, the best educational and well-made video I have ever seen about GD&T! I have been studying Mechanical Engineering for many years now and always had a hard time wrapping my head around some of these concepts still, the way you lay it out in the video is super intuitive! You also have absolutely fantastic animations, they are so clear, and precise and show accurately what is needed to get the point across. This is absolutely invaluable to anyone starting out with this! Thank you so much for all the time and effort you put into this!

    This is one of the clearest description of GD&T I've seen. Explains tolerance zones and geometry control tools pretty well. When trying to explain these to new engineers, I tend to use various shapes of pasta, or GD & spaghetti.
    Every time I saw a drawing with circularity or concentricity, it was because the part designer really wanted position instead. In any case, I heard the concentricity tool has been removed from the 2018 update of Y14.5.

  • @Robert8455
    @Robert8455 Рік тому +15

    This must be one of the best videos explaining GD&T. I started my career on a drafting board and then moved our company onto CAD in the late 80s' and it was a long time before ANSI Y14.5 creeped in and was finally adapted on new designs. We still had a long road a head to train everyone down stream on what these funny looking symbols meant. If we had something like this video way back then it would have been incredibly powerful. Well done. Absolutely love the clarity of the details and colors used to illustrate, the pace and smoothness of the presentation is excellent.

    I’m an apprentice engineer, just coming up on finishing my first year at the company I’m working for, and the other day a guy who works in design (a CAD expert) was helping me with some simple tolerancing, and said “you wait until you have to learn geometric tolerancing.” When I see him next, I don’t doubt I’ll be able to have a decent conversation with him about it, and this video has, at the absolute least, given me a massive step up on the other apprentices when it comes to CAD.

    I'd like to add that in practice, circular runout can list concentricity, circularity (when the datum feature applies as such), and co-axiality (as off-angle holes will very likely produce bad runout measurements).

    I’m a machinist for 25 years. Got my journeyman card. This is something I learned from that. Thank you for taking your time to show us. The formula to calculate true position.
    X2(power of 2) + y2(power of 2)= n square root of that divided 2. But you need a Texas instrument calculator.
    Always remember MMC is your friend.
    90% of the time. Checking parallelism. You can just use a Micrometer instead of placing your part on a granite surface and running your indicator. What if the part is thin n bow(not flat) . You now using flatness against you. But you bolt that part to the mating part. It straighten itself. That’s just my opinion. But what do I know . I’m just a machinist.haha

  • @faustinogarciachavero5016
    @faustinogarciachavero5016 Рік тому +1

    Congratulations.
    Very good explained video.
    My 5 cents:
    - 3:46, each letter refers a Datum Feature; and the letters (could be 1 or more) inside each box in the DRF establishes a Datum. (Video is correct while explain the particular example where each Datum Feature is used to establish each Datum, but more than one Datum Feature can be used together to establish a Datum.)
    - 23:34, Profile Tolerances can be used to control the form, orientation, location and size of Features, all at the same time. (Video is correct indicating Profile Tolerances can be used to control the form, orientation and location, but, probably anticipating a misconception of the concept of refinement of a FOS, avoids to indicate Profile Tolerances can also control size.)
    Great job.
    Thanks.

    This is the best GD&T explanation I've ever come across.

    I just took a CQE/ASQ test and, although I've passed the exam, if only I had come across this videos before taking the exam, it could've been a lot easier. Nice content.

    Although I already know these, it's still somehow very refreshing to relearn them, it's amazing how amazing you structured, narrated, and presented this topic, this is brilliant!!

      Virtual Worlds Timeline: Images from the Moon project, Active Worlds-1999. A virtual space museum and reconstruction of the space program vehicles including the Apollo XI moon landing in July 1969 created in the Active Worlds environment by a team from University of Cincinnati. Images show the "Virtual Walk on the Moon" online event with Apollo IX astronaut Russell Schweickart, held on July 21, 1999, thirty years to the minute after the actual landing on the moon.

      Does history really repeat itself, or can we learn from the mistakes of those who came before us? History provides a chronological, statistical, and cultural record of the events, people, and movements that have made an impact on humankind and the world at large throughout the ages

    Started working in metrology about a year ago. We have a set of part the has the 0,0,0, set for what seems to be a random place. The actual postion is actually related to the entire assembly. It not helpful because we dont have the rest of the assembly, nor do we have space for it. Then there is the part that uses a small cylnder as datum A, Datums B and C the inside of an oval shape hole on the X and Z axis. These are then used to measure the true position of pins and have the plastic moulded around them. Because we do mostly plastics, alignment can be tricky as we have to deal with mould split lines, flash and distortion that wont affect the final product. Yeah it will work but the department can't certify it as we can't get that warped thing to measure correctly because you put the spilt line on the only critical measurement/alignment surface of the entire prodcut.
    I don't ask me about out work load, mostly caused by previous people not really knowing what they were doing (I mean i dont either, but some of it is down right baffling). The number of parts that do alignmets from holding jigs if a little concerning, specially when that alignment isn't done everytime the measurement is run.... Yeah not great.
