Direct Numerical Control System

What is Direct Numerical Control (DNC) ?

In production situation, when several CNC machines are used it has become a common practice to use a central computer to connect all the programs at central place and to transfer the same to the CNC system when required.  This feature is called “DNC Lining.” User can directly access any program from the library of programs in the host computer. Transmission of message and other critical data are also possible.

Advantages of DNC System:-

  1. Sharing of computer time.
  2. Better storage of the programs.
  3. Operating costs are lower than with N.C.
  4. Programming is faster simpler and more flexible.
