Depending on the object and the extent of the surface you want to carve,
you might only need a simple 3-axis machine like a Taig, Grizzly minimill,
or similar. If you want an entire head or bust, you probably need at
least 4-axis capability, and a more sophisticated CAM program to
generate the coordinated 4-axis moves. I've heard of some people doing
this by selecting patches of the surface and cutting them at one setting
of the rotary axis, and then stepping some distance over on the rotary
and doing the next patch. The rotary axis can be a dividing head or
rotary table turned on its side, and mounted on the table of a conventional
mill.

For the most sophisticated stuff, you might need 5 or 6-axis capability,
but that gets insanely complicated to set up properly.
