Research Abstract

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.
