NX cam 4th axis wrapping machining
NX cam 4th axis wrapping machining
(OP)
Hi
I was wondering if i need the multi-axis machining package if i wanted to mill something like this:

http://www.youtube.com/watch?v=Lg62BrMLXgU
At the above video shown,they use a custom developed UDOP operation (from postprocessor.ru) which is not native to NX cam.
It's basically wrap a 2d geometry and fixed the Y axis (if rotary table axis is in Y) and transform the Y to rotary movement.So it's basically still 3 axis movement and not Full 4 axis.
Other software like Sprutcam does this, it's called Cylindrical Interpolation and Mastercam called it Axis Substitution.
I was wondering if i have 3 axis NX cam package, can i do something like above?
Thanks.

RE: NX cam 4th axis wrapping machining
If the geometry is already wrapped, then to program a path like this using surface contouring you would need a multi-axis milling license.
You could also program it flat with a 2.5 axis milling license, and do the axis interchange with an API program or in the postprocessor.

The above UDOP is developed by POSTPROCESSOR.Ru and I think it's not a free ware.
I wonder if the NX CAM developer would expand this functionality (the wrap feature) in the future for 3 axis milling package.
It's easier to perform a milling operation on a swept geometry (on CAD) then to do separate Axis exchange or postprocessor alteration like what you have mentioned above.
Other CAM system already has this feature that doesn't require multi-axis cam package (since it's only 3 axis movement)
Also, i read from the brochure that NX cam 3 axis package support 3 + 2 indexing milling. If it that so, then 3 axis package is enough for me. Price is one factor since multi axis machining package cost much, much more than standard 3 axis package.
Thanks again for your reply
