It is possible to estimate of cutting resistance in single tooth saw cut from fracture toughness that calculate with absorbed energy in impact- bending resistance in single tooth cut. Therefore, net power requiredment in circluar saw was estimated and invesitigated from absorbed energy in impact-bending.The results obtained in the study were ;1) Even it was not the same, estimated value of cutting resistance from fracture toughness with S&C method calculation was similar to experiment value.2) Estimated value of newt power requirement in circular saw was almost twice the value of cutting resistance estimated with S&C method.3) The estimated value of cutting resistance and net power requirement with S&C method bigger than experimental value is considered because the S&C calculation method should be used for metal material.From facts above, it can be said that to have a more accurate estimation of cutting rsistance in the MDF with the S&C method, the fracture toughness should be adjusted from 14.63Q^<0.5> becoming 8.387Q^<0.5> is equal to absorbed energy in impact-bending.

用单齿锯切冲击弯曲抗力中的吸收能量计算断裂韧性，可以估算单齿锯切的切削抗力。因此，本文从冲击弯曲过程中的能量吸收出发，估算和研究了圆锯片所需的净功率。1）即使它是不一样的，用S&amp;C法计算的断裂韧性估算值与实验值相近; 2）圆锯片的锯切功率估算值几乎是用S &amp; C法估算的锯切阻力的2倍3）考虑到S&amp;C法的切削阻力和净功率需求的估算值大于实验值，因为S &amp;C计算方法应用于金属材料。从以上事实可以说，为了在S&amp;C法的切削试验中更准确地估算切削阻力，断裂韧性应从14.63 Ω ^调整<0.5>为8.387 Ω ^<0.5>，等于冲击弯曲时吸收的能量。
