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.
