CNC Mill or computer numerical controlled milling device is used for automatically milling or cutting away at materials like wood, plastic, or softer metals such as aluminum based on a 3D computer model.
Akin to a 3D Printer, the CNC provides the ability to work with objects in x, y, and z dimensions. However, it provides subtractive manufacturing, rather than additive.
The sudo room sign by the intercom at the old 22nd st entrance was milled on such a machine!
The Noisebridge wiki contains much knowledge about using CNC mills for example TO MILL CIRCUITBOARDS: https://noisebridge.net/wiki/MaxNCMill#Toolchains
A big CNC machine with short Z height that we presently have
- JacksMill Jack gave us his CNC mill which we used to cut wood. It should also be able to cut soft metal like aluminum. It is located at the west wall, next to the robot control cabinet.
there is a large CNC machine suitable for soft materials like soft wood and plastic (and possibly harder materials?) located under the table in the southwest corner of sudoroom. It should work fine if plugged into the USB of a computer, and probably takes G-code commands through a USB serial interface, and probably runs Marlin or GRBL firmware. It's made of wood and acrylic, and the wood is painted white.

We had a small CNC Mill as of January 2015. It was donated by Pam and was traded away for a Quick Circuit 5000 (in the 3D printer area) It was a myDIYCNC link cnc thing
