Typical wood piece before router cutting Typical work done by a CNC wood router. 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 ...
The set up includes an air or electric driven router, a cutting tool often referred to as a router bit, and a guide template. Also the router can be fixed to a table or connected to radial arms which can be controlled more easily. In general there are three types of cutting bits or tools. Fluted cutters (used for edging and trimming)
A stone CNC router is a type of CNC router machine designed for marble, granite, artificial stone, tombstone, ceramic tiles, glass machining, polishing for arts and crafts, etc. Wood, metal and stone require different "bits" or "inserts". There is bit call as diamond tools with different diameter 4mm, 6mm, 8mm mainly used.
Most machine shops with lathes have many solid-HSS and solid-carbide tool bits as well as many insert-tipped tool bits, and most commercial operations that involve routers (such as cabinetry and furniture shops) use plenty of solid-HSS and solid-carbide router bits as well as some tipped bits.
While these speeds are fine for small router bits, using larger bits, say more than 1-inch (25 mm) or 25 millimeters in diameter, can be dangerous and can lead to chatter. Larger routers now have variable speeds and larger bits require slower speed. Drilling wood generally uses higher spindle speeds than metal, and the speed is not as critical ...
Router tables are used in one of three ways. In all cases, an accessory is used to direct the workpiece. A fence is used, with the router bit partially emerging from the fence. The workpiece is then moved against the fence, and the exposed portion of the router bit removes material from the workpiece. No fence is used.
