Definition of NC system, numerical control.
A system, which actions are controlled by the direct insertion of numerical data at
some point, is known as NC system.
In NC system, the numerical data, which is required for producing a part, is maintained
on a punched tape called as part program.
Definition of CNC, computerized numerical control.
Computer numerical control, CNC, is one in which, the functions and motions of a machine
tool are controlled by means of a prepared program, containing coded alphanumeric data.
CNC can control the motions of the work piece or tool, the input parameters such as, feed,
depth of cut, speed, and the functions such as turning spindle on, or, off, turning coolant
on, or, off.
Definition of DNC, direct numerical control.
Direct numerical control is termed as DNC.
DNC can be defined as, a manufacturing system, in which, a number of machines are controlled
by a computer, through direct connection and in real time.
