rotate a ploted 3d graph around an axis

[hosa200]

Hi ,
I am trying to make something like a CAM simulator , I started with a fixed object (cylinder) and a cutter (also cylinder) and i am trying to make the cutter to rotate around the axis of the cylinder and tangent to the top surface of the cylinder.
I attached the VI plus a video for what happened with me.

hi hosa200,

you might have missed to attach the vi.

ps: fill the controls with values, make them all default, so ppl trying to help you can play around, without guessing what values should be.

also don't forget to include subvis.

I update everything as you mentioned ,thank you

Your description of the cutter orientation doesn't quite make sense to me.  Is this what you mean?

The cutter rotation axis is perpendecular on cylinder rotation axis
like this

Ok, that is the way I interpreted your description but it didn't make sense from a machining point of view (coming from a non-machinist).  

Your x values remain the same in the second Matlab script but I think it should be your z values remaining constant.  I can't open your VI to make sure.

I am using Labview 2016 ,

Right.  And I am using 2012.  I can only see your picture and from there, I can't see which axis is x, y, or z.  Obviously, based on the video, you are changing the wrong values, so I am assuming that X is parallel to the top of the cylinder and should remain constant.

Sorry, I don't have a license of Mathscript to execute.  So assuming that your code for drawing the cylinder around the axis is correct (only the wrong axis was chosen), this is what I had in mind for the second MathScript node:

mXcut2=mXcut*sin((c*pi)/180);
mYcut2=mYcut*cos((c*pi)/180);
mZcut2 = mZcut;
