CNC routers, also known as CNC routers that are computer numerically controlled, are machines that cut or rout patterns of various shapes made from metals, wood, plastics and foam as well as a variety of different materials. They are able to cut mechanically complex shapes more quickly and with greater precision, accuracy, and repeatability than a human operator. 

They can be extremely helpful to industries like signs, cabinet manufacturing as well as plastics fabrication among other industries to tackle large tasks that require precise components quickly and efficiently. You can also know more about CNC routers via CNC routers are available in standard table sizes that range from 2' x 2' up to 5'x10 Some manufacturers also create custom machines that are 12-16 or greater. 

They've been around for quite some time however, they have gained popularity because of their improved performance and the advancements in software. 3D moves in Three Directions CNC routers are able to cut and move in three directions, commonly referred to as the X,Y, and Z axis. The X axis represents the left-to-right motion, while the Y axis is the forward-to-back movement, and the Z axis is upward or downward movement. 

Coordinates are entered in it by the operator or by a software program, and the movement can be controlled through the self-contained control system. Some come with the option for a vacuum hold down system that utilizes pumps to draw air over the top of the router to hold the material that is being routed.
