CNC (Computer Numerical Control) describes the process in which a computer converts the design created by CAD (Computer Aided Design) software into numbers. The numbers are considered as the coordinates of a graph and they regulate the movement of the cutter. In this manner, the computer controls the cutting and shaping of the material. CNC basically means to how a machine controls its basic method of movement.
CNC is a modern concept in the production and manufacturing industries. However, the concept of CNC dates back to the basic idea of NC (numerical control). The first commercial NC machines were built in the 1950's and ran from punched tape. While the concept immediately proved it could reduce expenses, it was so different that it was very slow to catch on with manufacturers. By the end of the 50's, NC was starting to get popular, though there were still a number of issues. These issues were soon improved with both analog and digital computers. The introduction of computer technology into the concept of numerical control led to what we now know as Computer Numerical Control.

CNC machining provides a variety of advantages to users as well as the customers to whom they are catering.
- Precise Component Machining: Computer Aided Design (CAD) software is used to create the 3D designs of the final component. When this is fed into the CNC machine’s computer, the machine is able to carve out the product from the material to exact specifications. Components of complex shapes can be created easily without consuming too much time.
- Range of Materials: CNC machining can be used to manufacture products from a variety of materials. These include bronze, steel, aluminum, as well as gold and silver. Polymers such as ABS, polycarbonate, and PTFE can be used with the machine as well.
- Repeatability: Once a design has been fed into the computer, the CNC machine can repeat the manufacturing process multiple times. Also, you will always get a high level of precision and intricacy in the component.
