The orthogonal cutting test of compact bovine bone was conducted, and the fracture behavior in micro cutting with chip formation was investigated by considering the effect on the anisotropic tissue. The result showed that the effect of anisotropic tissue was observed in formation of the continuous chip and the interrupted chip with the uncontinuous cutting surface. The chip formation was also similar to mechanics of that in cutting of the other anisotoropic material such as wood. Therefore, the shape of chip formation in the compact bone was categorized by types of flow, crack, shear and tear as classified in cutting wood. The effect of anisotropic tissue in shape of the chip formation was observed from some fracture types with crack propagation. Form these results, the fracture behavior in micro cutting of compact bone was suggested that the crack of type I might be progressed straightly along the osteon tissue in compact bone, another crack of type II might be curved on the outskirts of the osteon tissue, and the other crack of type III might be progressed severely in lamella of osteon tissue.
