A CNC wood router uses CNC (computer numerical control) and is similar to a metal CNC mill with the following differences: A wood router is controlled in the same way as a metal mill, but there are CAM and CAD applications such as Artcam, Mastercam, Bobcad, and AlphaCam, which are specifically designed for use with wood routers.
Typical three-axis CNC wood routers are generally much bigger than their metal shop counterparts.
Many of these machines with large drilling arrays are derived from CNC point-to-point borers.
These types of tables are typically used for nest-based manufacturing (NBM) where multiple components are routed from a single sheet.
Proper operation and maintenance in right way can greatly extend machine's life and reduce the incidence of failures.
