| Summary: | Insufficient crack growth resistance and durability of sapphire or ceramic materials are essential short coming which complicates their application in total human arthroplasty. One possible approach of elimination of this complicating is realized in a design of hybrid metal-bulk/ceramic-surface femoral head. In this context an actual problem appears. It is in machining without cracking in surface layer an internal surface in sapphire or ceramics spherical casing through the hole, which diameter is twice smaller diameter of processed sphere. The article represents the experimental investigation of diamond grinding of internal sphere in sapphire. It shows the effect of tool inclination angle and grinding conditions on both forces and roughness of machined surface. The conditions of low cracking in surface layer are identified. |
