State salient features of CNC machines.

1 Answer

Answer :

Salient Features of CNC machines….. 1. A part program can be fed to the controller unit through a keyboard. 2. The part program once entered can be used again and again. That is why the CNC controller is termed as soft wired control. 3. The part program can be edited whenever required. 4. For common and repetitive operations, a sub program can be created and called in the main program whenever required, thereby reducing the main program substantially. 5. The CNC machines have simulation facility whereby the part program can be checked for its accuracy without actual running the machine. 6. The CNC control unit allows compensation for any changes in the dimensions of cutting tools caused due wear or otherwise.
