Computer Numerically Controlled or CNC machinery is equipment designed to operate automatically by means of technology. With these routers, an operator creates a part design with an application that transfers the axis coordinates to the device. This piece of woodworking equipment is capable of cutting and shaping multi-dimensional pieces on a production line or in a workshop environment. CNC routers for woodworking typically have two to five axes used to perform specific cutting directions.
Computer controlled equipment can include a hefty price tag due to the accuracy and design possibilities it offers. A device may operate for hours or days without much human intervention. They are common in production environments where hundreds or thousands of the same wood parts are being crafted each day. Small woodshops can implement smaller two to three dimensional machines fairly easily with a little research.
Routing equipment offers one main advantage over hand operated device. Each production piece is completely accurate, meaning joints or other types of connecting pieces will fit together every time. Manually operated devices allow for inconsistency, and that is unacceptable in a manufacturing environment. This same inaccuracy can also cause immense material waste for small woodworking facilities.
