CNC Routers 101

CNC (Computer Numerical Control) is a computer "controller" that reads G-code and M-code commands and drives a machine tool by numerically interpolating the points along a cutting tools path and directing the servomechanisms that translate the data into movement.

In 1919 Oscar Onsrud and son Rudy built the first router, it was an air turbine powered machine. In 1928 they patented and over arm pin router that revolutionized woodworking factories just as CNC machines are doing today.

Small CNC metal cutting lathes and mills have been available to the home hobbiest for several years, CNC routers have finally become an option for the home woodworker. Small relatively inexpensive machines with fairly easy to use software are now available. CAD experience is not necessary, but definitely an asset when it comes to intricate work.

Some machines come with software for either PC or Mac computers, others are PC only, fortunately the latest Mac's are capable work arounds to run PC software.
