Abstract
The bone cutting is one of the important operative techniques in the field of orthopaedic surgery, and it is necessary to develop some new surgical instruments having high performance so as to meet the requirements newly arisen. For instance, the artificial hip joint made of ceramics requires a rasp of new type. To develop a new surgical instrument, it is indispensable to grasp exactly the cutting force of the human bone. The purpose of this paper is, therefore, to provide the bone cutting data for the design of new surgical instruments. The bone cutting forces were measured in orthogonal cutting by using various tool materials and cutting conditions.
