Numerical control (English name: Numerical Control abbreviation: NC) technology refers to the use of digital instructions composed of numbers, characters and symbols to realize the motion control of one or more mechanical devices. CNC is generally controlled by a general-purpose or special-purpose computer for digital program control. Therefore, CNC is also called Computer Numerical Control (CNC), which is called CNC in foreign countries. The concept of NC is rarely used.

 

 

        It controls the mechanical quantities such as position, angle, speed, etc. and the amount of switching related to the flow of mechanical energy.
