3-2-1 Principle - GD&T 4.0

[@shivprasad629]

The best video on 3-2-1 principle hands down !

[@tracyspencer2565]

Never having touched a machine. This video was so valuable. Thank you for the great visual.

[@lalitdubey7565]

This video amazing really, fist time I understand properly about 3-2-1 Principal , sir you great teacher. God bless you . Thanks

[@ku4uv]

I am currently learning CMM programming via on-the-job training. I couldn't fully understand the 3, 2, 1 alignment principal until I watched this video. This video helped tremendously! Thanks!

[@CHRISTABELRWATIZHA-pq3sf]

This is a great illustration! Thank you so much for the video. I feel it's important to note that motion in the positive x, positive y and positive z translational directions is not restricted by the 6 pins. The 3-2-1 principle restricts a total of 9 out of 12 degrees of freedom. That being said, we cannot add more pins as machining the workpiece would become hard. The remaining 3 degrees of freedom are restricted by clamps. I hope this helps

WOW! This was very informative! My brain needed this ❤️

glad it helped u

[@banothrajkumar6794]

Nice video explanation 👏👏👏

[@eodoherty47]

Brilliantly explained...!

[@pauldhinakaran1121]

What is the pre requisite of the input part so that we have less variation reference from 3-2-1...

[@FARSIDBINFARUK]

it was so helpful, my exm is on the day after tomorrow . it was an important topic. thanks for good explanation

[@don7229]

Glad it helped!

Glad you think so!

[@Tanujdabas]

Under rated video 🥺🥺🥺

[@SaiKrishna-pg7kz]

Best video ❤

[@Alitahirshayantahir]

Why 3 clamps were used in bottom side. It could be two only on diagonal position

[@don7229]

then object is free to rotate diagonally, forming an axis with these two diagonal points

[@amoldahiwal2077]

Very easy to understanding.🙏

[@imranihsan1400]

WoW, what a nice demonstration, may you kindly state difference between locate, support and clam, Bcoz I m confused in locate and support??? Clamp is clear in my mind

[@thestarkeyshow2443]

Smashed the video good job

[@don7229]

thank you....u too have great channel

Thank you

[@prash3084]

Brain undiscovered vanes of knowledge have been started by video 😂

[@sandeephasija8604]

Great Video! Thank you 🙏

[@NicknVio]

Well explained, so the 3 2 1 refers to restrictions deducting rotational or hor./ver translations.

[@don7229]

Yes, you got it right....

[@rcb8312]

Good

[@automech7733]

Thank you.

[@ismailgce]

Still movement in positive x direction and positive z direction not arrested.

[@arjunmohod6022]

This is compulsory bro otherwise how can we mount and unmount the workpiece

[@deepakjohsh7748]

Thats a good question! In order to answer this question, you will have to consider a total of 12 degrees of freedom, basically splittng the translational motion about positive and negative axis and Rotational into clock wise / Counter clock wise. This way the 3-2-1 principle will allow you to locate and support your work piece by arresting 9 DOF's. The remaining 3 translational movements are to be essentially arrested with a use of a Clamp. You might want to have look into design of jigs and Fixtures for understanding this concept.

[@trucvinguyen7671]

Love it!

[@don7229]

Thank you.....

[@b07_ashishsuradkar49]
