This document introduces CNC (Computer Numerical Control) machines. It explains that CNC machines use a computer to control cutting and shaping of materials according to a digital design. This allows mass production of identical parts in industries like automotive and aerospace. The document lists advantages like increased production rates and quality/accuracy compared to manual machining. It also notes some disadvantages like higher costs but lower skill requirements for operators. A variety of industries that use CNC machines are provided.

 Meaning of CNC Machines
 Why Use CNC Machines
 Parts of CNC Machines
 Advantages
 Disadvantages
 Applications

3. 1. In Industry it is not efficient or profitable to make
everyday products by hand.
2. On a CNC machine it is possible to make hundreds or
even thousands of the same items in a day.
3. First a design is drawn using design software, and
then it is processed by the computer and
manufactured using the CNC machine.
4. This is a small CNC machine and can be used to
machine woods, plastics and aluminum. In industry,
CNC machines can be extremely large.

4. CNC means Computer Numerical Control.
This means a computer converts the
design into numbers which the computer
uses to control the cutting and shaping of
the material.

7. Increase production throughput
 Improve the quality and accuracy of
manufactured parts
 Stabilize manufacturing costs
 Manufacture complex or otherwise
impossible jobs -2D and 3D contours

8.  CNC machines can be used continuously 24 hours a day, 365
days a year and only need to be switched off for occasional
maintenance.
 CNC machines are programmed with a design which can then
be manufactured hundreds or even thousands of times. Each
manufactured product will be exactly the same.
 Less skilled/trained people can operate CNC’s unlike manual
lathes / milling machines etc... Which need skilled engineers?
 CNC machines can be updated by improving the software
used to drive the machines
 Reduce waste as errors allows minimize wasted material

9. CNC machines are more expensive than
manually operated machines, although
costs are slowly coming down.
The CNC machine operator only needs
basic training and skills, enough to
supervise several machines.
