According to the wood processing apparatus and the wood processing method of the present invention, the tip of the wood to be processed as a work can be processed into various shapes that require it, and can also be processed three-dimensionally. In other words, by simply inputting the required processing pattern into the control unit, the conveyance (carry-in) and positioning, the positioning of the rotary blade, the cutting of the wood to be processed by the rotary blade, and the transport (unloading) of the processed wood are cycled. It is possible to carry out the work steps described above, and it is possible to automatically and continuously process various types of wood to be processed having different tip shapes on the same line.

For this reason, it is not necessary to perform manual work (carpenter work) or work using a single-function machine for each shape, which has conventionally been low in work efficiency, resulting in high work efficiency and reduction in manufacturing cost. Can contribute.
