Therefore, in order to process such a wooden board, in consideration of removing the damaged edge portion is cut to a size sufficiently larger than the actual size to be cut, and the unnecessary portion is cut back later. As an example, the initial wooden boards supplied initially have sufficient size and length, and the initial wooden boards are cut as necessary according to the design value. When the wooden boards are cut in a square shape of 100mm in width and length, After cutting the wooden board side of the square, including the rim, about 8 ~ 10mm longer than the actual one, change the direction of the separated square wooden board and remove the long cut again. Since this process is to adjust the length while moving the reference table 400, in order to perform the above operation process by fixing the reference plate 410 is positioned at 108mm from the cutter (330, 340) horizontal and horizontal from the initial wood board And / or a rectangular wooden board extending about 8 mm in length, and the unnecessary 8 mm can be fitted with an 8 mm thick splint (hereinafter referred to as a positioning bar; 500) to remove the damaged side in the correct range. The positioning bar 500 is to overcome the inconvenience of having to move the reference table 400 from time to time, it is generally widely used.

On the other hand, the plywood is usually coated with a wood powder or a plurality of wood boards with different grains and then coated to have a smooth surface with the effect of wood grain on the top and bottom surfaces. The larger the larger the rim of the initial wood board to form a protrusion protruding coating, the coating agent interferes with the contact with the positioning bar 500 to interfere with the precise cutting of the wood board, to remove these protrusions The work was inconvenient to be done before the foundation work.

Therefore, conventionally, after removing the projections through a mechanism such as sandpaper or grinder, the cutting work of the wooden board was made.
