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

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!

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

[pauldhinakaran]

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