Deutsch: Computerized Numerical Control / Español: Control numêrico / Português: Comando numêrico computadorizado / Français: Machine-outil à commande numêrique / Italiano: Computer numerical control
Numerical control (NC) is the automation of machine tools that are operated by precisely programmed commands encoded on a storage medium, as opposed to controlled manually via hand wheels or levers, or mechanically automated via cams alone. Most NC today is computer (or computerized) numerical control (CNC), in which computers play an integral part of the control.
