What are NC & CNC ?   Numerical control (NC) is a method of automatically operating a manufacturing machine based on a code letters, numbers and special characters. The numerical data required to produce a part is provided to a machine in the form of program, called part program or CNC (computer numerical control) 3
What are NC & CNC ?   The program is translated into the appropriate electrical signals for input to motors that run the machine. A CNC machine is an numerical control machine with the added feature of an on board computer. The computer is referred to as the machine control unit (MCU) 4
