Machining Cancellous Bone Prior to Prosthetic Implantation
The chapter describes the machining of compact and cancellous bone using a micromachining tool with a specially adapted spindle and the associated mechanics of chip formation. The chapter focuses on the design of the high-speed spindle, the structure of cancellous and compact bone, the theory of machining, chip curl modeling, the development of a biomachining center, and associated experimental results. The chapter concludes by stating that high-speed machining of compact and cancellous bone to prevent necrosis of the bone is possible.
