In the manufacturing industry, whether it is MP3 player, handphone, or hair dryer, there are some challenges. Consumers are very demanding and the competitors are very responsive to all these demands. At the same time, products are getting smaller and with more built-in functionality. Manufacturers must be quick in producing these products with a very short lead time and being more compact, the parts are also smaller. In order these parts can be assembled, they need to be more precise also. In order that these smaller, more precise parts can be manufactured faster and with more diversification, computers are used to machine these parts faster and with much precision. These computer machining applications is also know as Computer Numerical Control (CNC).

CNC-Computer Numerical Control
There are two common CNC processes, one is called CNC Turning and the other one is called CNC Milling.
CNC Turning is a machining process that cuts cylindrical workpieces.
CNC Turning can also be sub-divided into longitudinal turning, taper turning, facing and grooving:

CNC Milling is a machining process that cuts prismatic workpieces.
CNC Milling can also be sub-divided into pocket milling, contour (profile) milling, surface milling,
