NC(Numerical control)
Numerical control is a technique for controllingmachine tools or processes by using codedcommand instructions.
The CNC controller interprets these instructionsand converts them into two types of controlsignals
1.Motion control signals
2.Miscellaneous control signals

CNC(Computer numericalcontrol)
CNC is the numerical control system in which adedicated, stored program computer is built intothe control to perform basic and advanced NCfunctions.
CNC controls are also referred to as soft wiredNC systems because most of control system areimplemented by the control software programs

DNC(direct numerical control)
Direct numerical control uses a sharedcomputer to simultaneously control theoperation of a group of NC machine tools.
The main tasks performed by the computer areto program and edit part programs as well asdownload part programs to NC machines.

Distributive numerical control
The main concept of distributive numericalcontrol is to use a network of computers tocoordinate the operation of a group of CNCmachine tools.
Today many CNC machine together with robots,programmable logic controllers and othercomputer based controller, have been integratedinto DNC system to make automated
manufacturing systems possible
