GD&T Modifiers: MMC, LMC and MMB in practice

[@rickfearn3663]

Exceptional clarity. Thank you.

Thank You for a Great "Graphic-CAD/CMM Validation" for the Modifiers MMC-LMC & Datum MMB. Please leave the webinar Video on line as the Students at Chippewa Valley Technical College, would benefit from your work!

Excellent Webinar... You cleared all my doubts regarding LMC, MMC and RFS... Thanks a lot...

[@viswa1711]

Thank you both for the excellent explanation of MMC, LMC, MMB and LMB concepts

[@charlesdrury9712]

Sorry typo that should be I hope I did not offend you

[@flawns]

This is the biggest hurdle I have with GDT. Lots of examples how it works out. I have to see it to understand it

[@abdulsardar3769]

Thanks for understanding these concept very clearly...!!!1

Hello Creaform team. I found this webinar very useful and I aspire to apply for a job in your company in the Europe based office/ design center. Please suggest where to apply and are the vacancies available.

Best explanation. Thank you for this wonderful video!

Thanks for explaining shift concept & concept of Virtual condition help us to have Inspection pin of virtual size.. thanks cleared doubts 🎉

[@sathesh1600]

Excellent explanation. Thanks bro👍

Hi, Thanks for sharing this vedio. It will help us alot. After 37 mins, When we use MMC in datum B also. I didn't understand the method and result of using it. It would be so much helpful if you help me out to understand it.

[@stuartpilling2643]

I learned a lot from this especially up to the 30 minute mark when it changes to the brake disk example on MMB. For the first part my Position calculations don’t match and range from 0.89 to 1.366, however using the same maths for the second part with MMB applied they do match the 1.000/1.001 figures from the software. I don’t understand this part, any help would be greatly appreciated?

[@mohamedbilal864]

Thanks a ton! These are just gold..

[@MrSipi1988]

34:20 I can see at lot of cases that the B datum is marked with position tolerance relatively to A surface. In our case could we use perpendicularity either? I mean in that case they are the same, right? Do we have any advantage, disadvantage how it is marked? Thank you

[@MrSipi1988]

@@buffalobill8 Thank you, I need to fix to perpendicularity (or angularity) in this case.

[@manuboker1]

Wonderful Lectures ! Thanks.

[@tarzdan113]

Much appreciate for your effort!!

[@charlesdrury9712]

Wow I think it’s very interesting it looks like a person could learn a lot especially with the mechanical background and I truly hope I didn’t offend you with a little difficult with your accent and you’re talking real fast but apparently you’re very intelligent so I hope I did not send you God bless

[@a.garces5312]

Thank you very much for the excelent explanation. I have only a question, hope it is no stupid. Could we apply a MMB without a material modifier? For instance, could we have something like ¦ DIA .01 ¦ A ¦ B (M) ¦ OR do we NEED to go to ¦ DIA .01 (M) ¦ A ¦ B (M) ¦? I hope I made my question understandable enough. It is quite difficult to replicate the symbols. Thanks!!!

[@zaknefain100]

Does that fit the functionality of the assembly? A Feature of Size, without a modifier is a little strange in terms of functionality.

[@a.garces5312]

@@zaknefain100 I do not know. Never seen it. It is just an academic question. I am still learning and can't fathom all of the nuances of GD&T. Do you think it is possible or functional? Thanks!

[@pauldarthurs]

Theoretically, it may be possible. However, I think the important question is whether or not that would make sense from a functional standpoint. A case like the one you mention would imply that there is "play" on the datum, but no play on the feature itself. This type of case would most likely be quite uncommon.

[@GERMAN_GURU_ADITYA]

perfectly explained!!

Thanks!

[@pranav3813]

Unable to get the MMB concept properly, can anyone give link to video which explains is with practical example?

[@wickworth6167]

this helped me. kzbin.info/www/bejne/mp23i5SpgZxoaas

[@aKaCrowley]

IS this ISO or ASME?

[@peaceofmind6882]

Asme

[@rkmk1638]

I need to learn gd and t deeply

[@yogeshhadiya4479]

Excellant

[@huyphan9303]

thanks

[@41akc]

thanks but something is wrong. You make the part pass the inspection.. Not give the correct form or necesseraties.. such as you sad "carefully use LMC" that couse of lack of yellow ring. This is not a solution or unique cause of using LMC or MMC
