An Introduction to CNC Routers and More

By LarryReaves | April 10, 2009

In these down economic times, many fabrication companies are turning towards a technology known as CNC (Computer Numerical Control) routing. This technological transition has made CNC router operators one of the most in demand careers in America. But what exactly is a CNC router, who uses them, and what does it take to become an operator?

What is a CNC Router?

By definition, a CNC router is a machine-guided cutting or milling tool which can precisely and accurately carve materials in all three dimensions. The device does so by leveraging the power of a computer to position a tiny tool accurately along three different axes while simultaneously spinning that tool at upwards of 20,000 revolutions per minute. Thanks to the computer backing the system, a CNC router is thus capable of not only crafting intricate works such as fine wooden mantel pieces, but also highly valued orthopedic supplies.

Common materials used in CNC routers include, but are not limited to, woods, metals, and plastics. Each material has its own special type of CNC router, and thus has its own set of special operating instructions. CNC wood routers, for instance, typically have smaller tool tips and spin faster than their steel counterparts.

CNC routers also have other differences. For instance, some have multiple milling tips or routing tools.
