I really like SheetCAM

It works really well for what's commonly referred to as 2.5D (which is
what I do most of the time).

I documented the overall process that I use:

For full blown 3D stuff (like machining a human face), then you may
want to consider MeshCAM

It works for 2.5D stuff as well, but it isn't very efficient for those
types of parts.
