I've been thinking about buying a used mill and lathe for my basement. I work for a major manufacturer of metal cutting machines and would love to use / tinker with them in my spare time. One thing I've tried to search for / look into on youtube & elsewhere is cutting wood using a metal cutting cnc like a Haas or Makino. I find hardly an info on it. There must be a reason, no?

Is it because of price? Most of my "wood cnc" search results come up with routers that appear to cut mostly flat items. Nothing very 3d.

With some of the medium size horizontal cnc's I deal with, you could take a giant 3' diameter 4' high log and cut out a life size bust of Trump if you wanted to. It might not have any practical use but it could be a real attention getter.

If someone wanted to do that with like an A51 Makino (YouTube) I think it would be capable in theory, but why are people not using wood as a material in big machines like this?
