CNC don't print; they're subtractive. If you know how to design furniture, lay out and nest the parts, and program a CNC, they are the most wonderful tool in the shop.

CNC is computer numeric control. It is used in both subtractive and addative manufacturing processes, as well as in general automation (such as an assembly line robot arm).

Edit: "Machining" is specifically subtractive processes, which may or may not employ CNC.

I program and manage CNCs for a living. They are subtractive: they remove material; they don't add it. The abbreviation is not merely literal; its used to denote machining. You could call a 3-D printer a CNC, but they're not actually called that.

Yeah, but this thing literally can't ever nest :)
