For the poor machining performance of engineering ceramics， the surface/subsurface is prone to processing damage， which significantly impacts the service performance and fatigue life of engineering ceramic parts， the grinding damage formation and evolution mechanism of engineering ceramics are elaborated from the aspects of strain rate effect and material constitutive relation models. Based on this analysis， the influencing factors and the regulation of the grinding damages are analyzed. Then the suppression strategy of grinding damages is investigated in two aspects： grinding tools and processing technology. Finally，a brief outlook on the future development direction of key technologies for grinding damage suppression is presented.
