'''Computer numerical control (CNC)''' is the operation of any kind of tool by a computer using commands stored on a tape or disk. Typical CNC machines consist of a plate capable of moving in the X and Y dimensions with a '''tool spindle''' moving in the Z dimension. Movement in each dimension is controlled by a computer operating highly precise [[step motor]]s or, in older machines, motors connected to various transmissions capable of translating large movements into extremely small and precise movements.
Because of the great versatility of CNC machines, any number of tools can be attached to the tool spindle. When working with [[metal]], the tool spindle may consist of a [[power drill|drill]] bit or other cutting tool, or even a [[laser]] or [[plasma cutter]]. When working with [[wood]], the tool spindle can be a drill or [[router]] bit, or a [[saw]]. When working with [[fabric]], the tool spindle can be fitted to pin, cut, glue, mark, [[sew]], or embroider fabric. The CNC machines' versatility has made it ubiquitous in [[manufacturing]] applications, as it makes extremely complex operations cheap, accurate, and highly repeatable.
