CNC routers can perform the tasks of many carpentry shop machines such as the panel saw, the spindle moulder, and the boring machine. They can also cut joinery such as mortises and tenons. A CNC router is very similar in concept to a CNC milling machine. Instead of routing by hand, tool paths are controlled via computer numerical control.

Lutterloh-System is a pattern-drafting system intended for home pattern-cutting sewing.It was developed in Germany in the 1935 by Luise Aigenberger - later Lutterloh. Her grand-children run the company with Marcus Lutterloh and his Mother being chiefly responsible for the creation of the designs; Frank and Ralph Lutterloh run the USA and German outlets.
With the "rip" tooth pattern, the edges are sharpened at right angles to the cutting plane, forming chisel-like cutting surfaces, whereas crosscut teeth are sharpened at an angle, so that each tooth has a knife-like cutting point in contact with the wood. [1]
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.
The cutting edge of each tooth is angled in an alternating pattern. This design allows each tooth to act like a knife edge and slice through the wood in contrast to a rip saw, which tears along the grain, acting like a miniature chisel. Some crosscut saws use special teeth, called rakers, designed to clean out the cut strips of wood from the ...
