Although the existing wood board cutting machine can complete the cutting of wood boards, wood is processed into boards through various cutting machines so as to be made into various wood products such as floors, bed boards, door boards and the like. The cutting process has many factors affecting the cutting effect, such as the influence of the weight of the wood itself and the influence of the internal stress of the wood itself. Trees are not of uniform density everywhere when they grow, and therefore often uncontrollable deformation of already cut parts of the timber occurs.

After the wood board is deformed, the wood board may be scraped to parts near the workbench, and other parts are damaged; or due to the fact that the space in the saw path is too small, sawdust and glue of the makeup cannot be effectively discharged and is attached to the sawteeth, and cutting is affected; or the cutting tool is stuck in some parts, so that the cutting direction deviates, and the situations of beveling, side cutting and the like occur, thereby generating secondary waste products. If the wood board is completely stuck in the workbench, a worker has to completely stop the machine and take the wood board out of the workbench, so that the production progress of a production line is delayed; the plank that warp also can cause the damage to the saw blade, and the saw blade maximum width that the cutting machine used is 27-150mm, saw cuts the in-process saw blade and moves at a high speed with 25 meters per second to 70 meters per second linear velocity, if inside bending after panel cutting, can increase the frictional force that the saw blade received, leads to the temperature of saw blade and panel to further rise, and the cutting plane of panel probably consequently scorch blackens, and the surface is coarse, and the timber that blocks completely also probably directly blocks the saw blade.
