Difference Between NC and CNC

In this post, we will understand the difference between NC and CNC −

NC (Numerical Control)

It stands for Numerical Control.
The input mechanism is punched tapes and punched cards.
The modification in the machine programs can be done by changing the information on punched cards.
The operational parameters can’t be changed.
There is no memory to store instructions in them.
It is less expensive.
It requires very less maintenance.
It is moderately accurate.
The operators using this need to be highly skilled.
It is not very flexible.
It consumes more time.

It stands for Computer Numerical Control.
The input mechanism is that the program is fed data with the help of the keyboard.
The machine programs can be modified using computer.
The operation parameters can be changed.
It contains memory to store instructions.
It is very expensive.
It requires high maintenance.
It is accurate.
To operate it, not much skills are required.
It is highly flexible.
It consumes less time.
