===CNC
CNC stands for Computer Numerical Control. CNC mills or routers include proprietary software which interprets 2D vector drawings or 3D models and converts this information to a [[G-code]], which represents specific CNC functions in alphanumeric format which the CNC mill can interpret. The G-codes drive a [[machine tool]], a powered [[Machine|mechanical device]] typically used to fabricate components.<ref>{{Cite web|title = Five CNC Myths and Misconceptions {{!}} Modern Machine Shop|url = http://www.mmsonline.com/columns/five-cnc-myths-and-misconceptions|website = www.mmsonline.com|access-date = 2016-02-17|first = Mike|last = Lynch}}</ref> CNC machines are classified according to the number of axes that they possess, with 3, 4 and 5 axis machines all being common, and industrial robots being described with having as many as 9 axes. CNC machines are specifically successful in milling materials such as [[plywood]], [[plastics]], [[foam board]], and metal at a fast speed. CNC machine beds are typically large enough to allow 4' × 8' (123 cm x 246 cm) sheets of material, including foam several inches thick, to be cut.
