Metal Cutting using CNC Router


I am wondering if a CNC Router can be used to cut 1/8" or less thickness aluminum.

Although my shop is primarily a wood working place, I do get into some metal stuff at times (I have gas and electric welders, drill press, etc) and I am in the process of restoring a 1952 Piper Tri Pacer airplane at the moment. I want to design and build (I have AutoCAD 2011) a new instrument panel for the airplane as well as some other small aluminum parts. None of these would be more than 1/8" thickness material and likely not even that.

Anyhow, I was wondering if I could install a milling bit in the router and use it to cut this lightweight, relatively soft aluminum. Does anyone have experience with that?

Most any CNC router can cut 1/8" aluminum. One of the most popular posts on my CNCCookbook blog is 10 tips for cutting aluminum on a router:

Ideally, you want a single flute cutter for aluminium in a router type machine, and you need to get the revs right, as well as the feed.
If the CNC can move slow enough and you have the right bit then 1/8" metal shouldn't be a problem. You'll need something like this that will fit your router.
