Machining Cancellous Bone Prior to Prosthetic Implantation

Abstract

The chapter describes the machining of compact and cancellous bone using a micro machining 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 modelling, 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.
