The relative movement of the wood by the tool acting on the wood to obtain a certain shape, size and surface state of the wood product processing process. It is a basic process with a large proportion i in wood processing, and its quality has an important influence on the gluing process and the surface decoration process. The mechanism of wood cutting involves the mechanical properties of wood, the material of the tool and its processing method and geometry, the relative movement of the tool and the wood processing part, the mechanism that realizes a certain movement, and the cutting force, etc., which have been the basis of production practice and scientific research Form an independent discipline on top.
