CNC Controller ToolsOctober 22, 2016
Numerically Controlled (CNC) machines were introduced in the late 1940’s and early 1950’s and were used for all machine control and data processing before the advent of microprocessors or computers. Computerized Numerically Controlled (CNC) controllers are sometimes still refereed to as NC controllers. An NC controller receives a set of sequenced instructions, the program, consisting of alphanumeric characters. The controller then uses this set of instructions to direct the motions of a machine tool such as a milling machine, lathe, plasma cutter and of course router, much like the controllers today.
