摘要：
In order to achieve quality and efficient grinding processing of engineering ceramics, the high-speed deep grinding mechanism and the material damage mechanism of engineering ceramics are systematically studied. Then the mathematical model of grinding forces is proposed, and it is verified by experiments. The results show that the model calculated values consistent with the experimental results in trends, and values are very close. It indicates that grinding force depends on material removal modes, mechanical properties and grinding conditions. When ceramics are removed in ductile mode, the higher the microhardness of the material is, the greater the grinding force will be. When materials are removed by brittle fracture, the higher the fracture toughness and the lower the microhardness of the material, the greater the grinding force. The grinding force decreases with the increase of wheel speed and the decrease of feed rate or grinding depth. Different materials removal modes lead to different influence degree of grinding parameters on the grinding force, and the influence of grinding parameters on the grinding force for material ductile removal are greater than that for material brittle fracture removal. © 2011 Journal of Mechanical Engineering.
