Editing Router (woodworking) (section)

== CNC router ==
A [[CNC wood router]] is a computer controlled machine to which the router or spindle mounts. The CNC Machine can be either a moving gantry style, where the table is fixed and the router spindle moves over it, or fixed bridge design, where the table moves underneath the router spindle, or hand-held style, where the operator moves the machine to the area to be cut and the machine controls the fine adjustments. [[Computer-aided design|CAD]]/[[Computer-aided manufacturing|CAM]] software programming is used to model the part that is to be created in the computer and then create a tool path for the machine to follow to cut out the part. The CNC moves along three axes (X-Y-Z). Most CNC routers have a three motor drive system utilizing either servo or stepper motors. More advanced routers use a four motor system for added speed and accuracy.
