    - The control unit of NC machine tool works in batch processing mode and the control unit of CNC machine tool works in ON-line mode

    - Computer Numerical Control (CNC) system is nothing but the Numerical Control (NC) system with a microcomputer or microprocessor using software to implement control algorithms.

    - The principle functions of CNC machine tool are as follows:

    1. Better diagnostics
    2. In-process compensation
    3. Improved programming and operating feature
    4. Machine tool control
