You are very unlikely to find any manufacturing field that doesn’t use an automated CNC (Computer Numerical Control) machine.

A CNC machine is a must-have for any individual working at or owning a manufacturing corporation. Today, there is a high demand for these machines, as they have a wide range of applications in various industries.

So as to fulfill all these demands, training programs have been created to educate people on the processes and operations of CNC machines. You can find out more about CNC machines on this page.

The first NC machine was developed in the 1940s. It relied on the technology of telecommunication data storage. This technology is sometimes referred to as punched tape technology. After the 1950s, punched tape started to become outdated, and data technology quickly shifted to digital computer processing.

In prototype development, CNC mostly relies on instructions that are in digital form from CAD (Computer Aided Design) files. The CNC machine interprets the design as directions for cutting archetype parts.

Programming computerized devices to precisely control the tools of a machine greatly improves shop productivity by automating technical and labor-intensive processes. Automated cuts improve the accuracy and speed in which prototype parts can be created.


CNC machines can effectively do forming, grinding, DIY projects and other tasks, and can do the job of lathes, mills, routers and grinders.
