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.

CNC (Computer Numerical Control)

• 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.
