Abstract
This paper describes the results that the process of chip formation analyzed by behavior of cellular deformation in cutting of wooden porous material, comparing with that of aluminum in non-porous material. The analysis results showed that the shear angle in cutting of wooden porous material changed in range of approximately eighty degree, whereas that of aluminum changed in the range of approximately forty degree. The result also indicated that the value of shear angle in cutting of spruce wood was different among some analyzed methods, whereas that of aluminum agreed with each other. When the deference analyzed between the wooden porous material and aluminum was discussed in mechanical condition of shear zone, the value of shear angle which analyzed from the deformation of individual cell wall was peculiar to that of mechanical condition. From above results, it was suggested that the method analyzed from the deformation of individual cell wall was effective in estimation of shear angle.
