Abstract: The structure of compact bone is heterogeneous and as such, is difficult to shape by cutting tools during clinical surgical practices. The structure of bone can have a devastating effect on the performance of the cutting tool unless it is coated with a thin solid film that is wear resistant. The paper investigates the use of diamond coated cutting tools to prepare bone for prosthetic implants and the implications of their use on the machining characteristics of biological materials.

Keywords: diamond tools; medical materials; compact bone; diamond coatings; microtools; micromachining; cutting tools; prosthetic implants; machining characteristics; biomaterials.
