抄録

Some differences of the cutting phenomena caused by materials and hydrous property in the cortical and cancellous bones are discussed in this paper. They are summarized as follows. (1) Although the cutting behavior with brittle fracture is observed in the dry cortical bone, the continuous chip formation is observed in the wet cortical bone even if a large depth of cut is applied in the cutting. From this result, it is suggested that the property of wet bone may be changed by the contained water. (2) It is easy to form the continuous chip even in the across cutting direction on the wet cortical bone section, which is difficult direction to cut, because water in the bone may increase toughness of the bone tissue. (3) Cutting of the trabeculae in the cancellous bone is brittle and soft cellular tissue in the trabeculae is easy to deform. But soft adhesive bone materials is discharged on the tool rake surface as a cutting chip. Consequently, it seems that the behavior of cutting and the chip formation for cancellous bone depend on the soft tissue.
