2. Write any four advantage of NC machine.
3. Enlist any four components of DNC machine.
4. Write any four application of NC machine.​

Answer 1

Answer:

2. Advantages of NC

Reduced manufacturing lead time – the job can easily and quickly set up with NC. Reduced non-productive time – In case of complex machining NC seems helpful to reduce the non-productive time. Because of quick/ automatic tool changing, quick setting up, and reduced workpiece handling time.

3. The basic DNC system needs following the basic components are the mainframe computers, memory, communication networks, NC machine tools.

4. Applications of numerical control technology

Numerical control technology has application in a wide variety of production operation such as metal cutting, automatic drafting, spot welding, press working, assembly, inspection, etc. However, NC finds its principle application in metal machining operations.
