CNC router tool

A CNC wood router is a CNC router tool that creates objects from wood. CNC stands for computer numerical control. The CNC works on the Cartesian coordinate system (X, Y, Z) for 3D motion control. Parts of a project can be designed in the computer with a CAD/CAM program, and then cut automatically using a router or other cutters to produce a finished part. The CNC router is ideal for hobbies, engineering prototyping, product development, art, and production work.

Some wood routers have multiple separate heads that can come down simultaneously or not. Some routers have multiple heads that can run complete separate programs on separate tables all while being controlled by the same interface.

The wood router typically has 6" 10" air ducts to suck up the wood chips and dust created. They can be piped to a stand alone or full shop dust collection system. Some wood routers are specialized for cabinetry and have many drills that can be programmed to come down separately or together. The drills are generally spaced 32 mm apart on centres a spacing system called 32 mm System. This is for the proper spacing of shelving for cabinets. Drilling can be vertical or horizontal (in the Y or X axis from either side/end of the workpiece) which allows a panel to be drilled on all four edges as well as the top surface. Many of these machines with large drilling arrays are derived from CNC point to point borers.

The wood router typically holds wood with suction through the table or pods that raise the work above the table. Pods may be used for components which require edge profiling (or undercutting), are manufactured from solid wood or where greater flexibility in production is required. This type of bed requires less extraction with greater absolute vacuum. A second type hold down uses a spoil board. This allows vacuum suction through a low density table and allows the placement of parts anywhere on the table. These types of tables are typically used for nest based manufacturing (NBM) where multiple components are routed from a single sheet. This type of manufacturing precludes edge drilling or undercut edge work on components. Vacuum pumps are required with both types of tables where volume and "strength" are determined based on the types of materials being cut.
