Hi guys,
I come from a 3d milling setup. Who do I use kinematic 6axis (robot arm) let say to do sculpture.
Do I take the 3d cad plug it in and the kinematic will translate my 3d (3axis was work for milling) into a 6axis robot arm ?

That rather depends on what the CAM package outputs.
But LinuxCNC is capable of converting XYZABC coordinates into robot arm joint angles.
Have a play with the Puma demo configs (they have a virtual on-screen machine, no hardware needed)
sim/axis/vismach/puma

You have very interesting question about robot control.
I have experience with Robots KUKA and different jobs similar as you need.
I thought about your question also in the past but didn't anything.
The most hard way it to make your own kinematic, I suppose, because robot has many indeterminate positions, for example in 0 and 180 grads of elbow positions, you will see it from inverse kinematic formulas.
The easiest way is to use for example Power Mill Robot plugin. Build there model of your robot.Then build post processor that will give outputs of grads for each your axis and to use it linuxcnc. In this plug-in you will also has simulation of processing work. It's very convenient.

LinuxCNC contains both a specific kinematics for Puma style robots and a general kinematics for any serial robot (genserkins)
It is likely to be easier to use these than to write something from scratch.
