Ғылым және технология

Quickly understand how Maximum Material Condition (MMC) works when using GD&T to control the position of clearance holes.
Here's a link to a screenshot of the whiteboard:

This video was created to help beginners rapidly understand GD&T and quickly use the concepts in practical applications. Technical vocabulary was purposefully NOT used in an attempt to convey these topics to those who do NOT have a background in GD&T.

    Hi there Trayjan00! I'm glad you found this useful! I find that a lot of times GD&T is taught from a theoretical perspective and it can be hard to then apply it to practical scenarios. I hope the mini-assembly was useful in understanding how MMC can be applied to clearance holes from a practical perspective. Remember, MMC is a great tool to use any time you are dealing with any type of "Clearance" feature (where one features fits through or in-between another feature). MMC preserves functionality while giving the overall design and machinist additional tolerance to take advantage of just by modifying the size of the features. This is something that you simply can't do with traditional plus/minus tolerancing. Have a great weekend and stay safe and healthy!

    I've been a mechanical engineer for over 25 years and your explanations of these concepts are the best I've ever seen. The bad news is that you don't produce enough videos and the sound quality is not the best. I watch many videos across many subjects like sailing, dirt bikes, cars, drones, welding, law and machining. A common thing I have seen on all of the channels is that the production quality improves over time likely due to added resources based on increased ad revenue. It's like a circle of improvement....improve quality, more viewers, more money, better equipment, etc. Many content producers underestimate how important good sound is on a video. The thing that most do that you aren't is that most produce videos on a regular basis. Regularly releasing new content motivates people to subscribe which drives increased revenue......blah blah blah. Your niche and teaching style makes your YT channel primed to take off if you just keep at it.

    Hello kslats916! First, thank you for watching! Second, thank you for taking the time and interest to write such a helpful comment! You took time out of your day to write a longer comment that was full of very useful and motivating critiques! I am also a mechanical engineer as well as a maker, a welder/fabricator, machinist, and all-around curious person. I dive into numerous topics and sometimes it is difficult to find enough time in the day to follow all of my passions including creating videos on GD&T. I am, however, hearing from numerous people that they think this channel could expand and be something great if I invest more time in it and so I am planning on devoting more time to it here going into the future. Thank you again for watching and for providing the motivational critique and uplifting words of encouragement!

    this is one of the best explanation I have seen for the topic. Thank you @Straight To The Point! 'The given value of the position tolerance is to be considered as the INITIAL value, when the feature is at its MMC condition' and then we have to 'ADD the diameter deviation value to the given position tolerance and use it as a BONUS tolerance' were the key points of my understanding from your explanation.

  • @skankhunt-zw6gg

    that second advantage of using the MMC condition is also well understood. My understanding is as follows. Since we can't change the hole positioning after it has been drilled, before throwing the part, at least we can do is to see the ALLOWED hole diameter for the current (deviated (already drilled)) position of the hole from the chart, and then enlarge it to that particular (allowed) hole diameter.

    Hi skankhunt42! First, I see you man! I appreciate your various quality comments on several of the videos so thank you! Second, your takeaway from the video is perfect! How much the hole diameter size deviates away from its MMC size is considered "bonus" tolerance and so that means you get to add that amount of deviation to the position tolerance. Obviously this does not go on forever as you are not allowed to machine the hole any bigger than what the size tolerance states. So once you reach the maximum hole size allowed you have to stop there. Otherwise the part will fail due to the hole size being too large. Thanks again for watching and for the awesome comments! Stay safe and healthy!

    Hi there Nachiket! Thank you for watching and for the uplifting comment! I am continuing to shoot more videos and posting them and I will be doing so on a regular basis. I do have two more videos covering the two different methods for correctly calculating the clearance hole diameters that you see in this video. So check them out! Thank you again for watching and commenting! Have a wonderful day!

    After searching for so many videos in you tube, this one is very clear and cleared all my doubts. Volume is too low but thats okay. Please increase the volume next time.
