The influence of various factors on the cutting force structure of the wood texture wood workpieces uniform. Therefore, when handling workpieces kinds of cutting and, hence, the angles of meetings in different parts of the cutting uneven edges, especially on areas with construction defects of wood.

When cutting wood resists the action of the tool *, to overcome that should be attached to the tool a force. The magnitude of cutting force depends on the breed of the treated wood, the type of cutting, the cutting angle, rear angle, visual tool. If you assume approximately uniform wood isotropic material, the magnitude of cutting forces will increase in proportion to the width of the cut chips. If we take the cutting force during machining of pine as a unit, the cutting force in the processing of alder, birch, beech, ash and oak will be respectively 1.05, 1.25, 1.4 and 1.7, and in the processing of lime, aspen and spruce – 0.8, 0.85 and 0.95.
Cutting force increases with cutting in the face, reduced – by cutting across the grain. If we take the effect of cutting across the grain per unit, by cutting along the grain, cutting force increases by about two times, when cutting into the end – six times. With the increase of the cutting angle cutting force increases. For example, after cutting a piece of dry pine shavings thickness of 0.1 mm with increasing the cutting angle from 45 to 70 cutting force increases with cutting across the grain of 1.1-1.3 times, while cutting along the grain and in the end, respectively, 2 and 1.5. After cutting chips of 1 mm thickness, this dependence is preserved under cutting across the grain and in the end, when cutting along the grain, cutting force increases by a factor of 4. The value of the posterior angle affects the value of cutting force only when it is very small. In this case, the tool itself dominates under wood fibers, which after passing through the cutter gradually straightened. There is a so-called elastic recovery of fibers, which increased their pressure on the rear face.
As a result, the force of friction on rear face cutter, opposing its promotion. On the cutting force affects blunting of the tool in the process. The more blunt chisel, the more the resistance increases timber cutting, the greater the must be applied cutting force. And the thicker the chip, the less impact on the strength of blunting the cutting blade, so when cutting thin shavings should be particularly concerned about the sharpness of the tool.
