Finish diamond machining of ceramic femoral heads

In the present paper reported is the manufacturing of ceramic spherical implants for medical purposes by employing diamond-abrasive lapping techniques. The technological parameters of this technique and a theoretical model experimentally verified are presented. A novel method of control of the free lapping process is suggested, resulting, as indicated by the experimental and theoretical results, in a decrease of time requested for the coordination of the profiles of the tool and the workpiece and in an increase of the process efficiency when manufacturing precision work surfaces.
