It's been 20 years since I wrote any CNC controller software but the "assembly language" of CNC then was g-code (http://en.wikipedia.org/wiki/G-code).
In the end it really doesn't matter how your CAM software stores its data as long as you can translate it to g-code within the software or with a 3rd party compiler. The fun part for me back then was optimizing that translation with respect to the machine's capabilities so you can do things like minimize machining time while maximizing tool life and keeping surface roughness within tolerances.
