Methods of metallic prostheses manufacturing using numerically controlled machine tools are proposed. Specific difficulties arising in the integration process of CAD and CAM modules are presented and methods for improvement are proposed. Requirements for up-to-date CAM systems pertaining to driving the tool across the complex shape surfaces are summarised and the demand for additional software to bridge the gap between the CAD/CAM and the given CNC machine tool controllers is determined (postprocessing). Attention is paid to NCprograms verification techniques using substitute materials for the machining process and rapid prototyping. Limitations of the proposed method due to its relatively low productivity and the shape problems are defined, and ways of overcoming them are suggested. The results of practical experiments leading to prototype manufacture are described. The areas of problems caused by the specific kinematics of the applied CNC machine tools, as well as problems of handling large amounts of data flowing into machine control units are mentioned.
