中文摘要：

建立了多颗粒金刚石小砂轮轴向进给磨削工程陶瓷的磨粒运动轨迹模型，通过改变砂轮转速、陶瓷件转速、轴向进给速度，揭示加工参数变化和磨粒运动规律的关系。通过不同加工参数下实际的陶瓷加工实验，分析了进给速度对边缘碎裂、磨削力、金刚石磨粒耗损的影响规律，得到的实验分析结果和仿真结果一致。实验运用了合适的实验方案和测力系统，并利用边缘检测和轮廓曲线拟合的方法实时追踪检测金刚石顶尖曲率半径变化来定性分析金刚石磨粒的磨损情况。研究结果为如何利用合理的进给速度控制陶瓷材料的边缘碎裂，减少工件和砂轮磨具的损伤提供了借鉴。

英文摘要：

An abrasive grain trajectory model of grinding engineering ceramics in axial deep creep-feed grinding with small grinding wheel was established and the relationship among cutting parame-ters and the law of abrasive grains＇motion was revealed.The effects of feeding speed on the crushing of edge,grinding force and the diamond abrasive wear were analyzed according to the actual machining of ceramics by changing processing parameters.The experimental results are consistent with the simu-lation ones.Experiments were based on appropriate experimental schemes and force measuring sys-tem,the changing of the diamond grain＇s curve radius was real-time detected by edge detection and curve fitting of profile.This paper also provides references on how to use the feed speed that is reason-able to enhance the processing efficiency by removing ceramic chunks via the splitting and to reduce the damage on the workpiece and the grinding wheel.
