摘　　要：通过选用氮化硅、氧化铝和氧化锆3种陶瓷材料进行单行程磨削实验和表面破碎损伤观测实验建立了表面破碎损伤模型。运用该模型,根据磨削输入参数可以预测和控制陶瓷的磨削损伤,从而可以优化陶瓷磨削过程,提高磨削效率、降低加工成本和降低加工损伤。Grinding using diamond wheels is the most important method for machining engineering ceramic because of its high hardness and brittleness. But in a grinding process, ceramics generate an intense grinding force and render surface damage. Surface damage caused from the grinding can reduce the intensity of the work piece and affect the surface quality. In order to suppress surface damage, a model for the surface fragmentation damage was established in this work based on the one-way trip grinding experiment and surface fragmentation damage observation of Si3N4, Al2O3 and ZrO2 ceramics. By inputing grinding parameters into this model the surface damage can be predicted and controled. This allows optimization of the ceramic grinding process by which we can increase the productivity, and reduce the grinding damage and the processing costs.
