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!
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, 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
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.
The best video on 3-2-1 principle hands down !
Never having touched a machine. This video was so valuable. Thank you for the great visual.

This video amazing really, fist time I understand properly about 3-2-1 Principal , sir you great teacher. God bless you .
Thanks
Your explanation along with this demonstration made it easier to understand this concept
Very informative! Thanks a lot !!!
excellent video
nicely animated and explained
Very good video and very informative. Thank you Sir. I understood the concept of GD&T only after watching this video.
WOW! This was very informative! My brain needed this ❤️
Glad you liked it!!...u too have creative content..
Yoo
Oo noo !!
Are ama college ku asa bhalase bujhiba
wow
Great Video! Thank you 🙏
Damn 😮
Thanks for making it so simple sir❤

Keep em coming!
More to come!
finally cleared the doubts with visually , thanks.
glad it helped u
Amazing..!!!
Wowwwww top video
Best explanation and u cleared all doubts on 3-2-1 principle.Thank you....
Glad to hear that
Nice video explanation 👏👏👏
Best video ❤
Very use full information
Love it!
Thank you.....
Better explaination 👌
Very easy to understanding.🙏
Very Nice Lecture
Thank you ❤

ভালই হয়ছে,,
WOW this is amazing explanation thanks a lot
Thanks
Thank you.
I have so much to learn from you my wonderful friend.
God bless :)
thank you so much
@@don7229 You are most welcome my friend 😊😊😊
Under rated video 🥺🥺🥺
this was very informative.. 🤝🤝
Glad you think so!
awesome .. keep safe always new friend here

What is the pre requisite of the input part so that we have less variation reference from 3-2-1...
Thanks
Wow man very nice explanation
Thanks
Very nice...👍
Thank you! Cheers!
Very nice..thank you
Thank you too
SUPER ANIMATION
thank you
This was very interesting 💯🐸
thank u..
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
Cool , 👍👌, v.helpful
Glad to hear that
Keep it up
Thank you
nice one
Thanks
Brain undiscovered vanes of knowledge have been started by video 😂
Super video
Thanks
Nice.
Thanks!
Well explained, so the 3 2 1 refers to restrictions deducting rotational or hor./ver translations.
Yes, you got it right....

Wow
Thank 5 sir
new friend here ✌️
thank you stay connected
Thanks for your subscription bro... I did you to

Why 3 clamps were used in bottom side. It could be two only on diagonal position
then object is free to rotate diagonally, forming an axis with these two diagonal points
Still movement in positive x direction and positive z direction not arrested.
This is compulsory bro otherwise how can we mount and unmount the workpiece
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.

is 2 refers to holding(clamping),
Not exactly
