摘要:
分析磨削氮化硅陶瓷材料时产生的磨削力，对磨削力的变化规律进行探索，对磨削过程中磨削力的大小进行预测，提高磨削效率和加工表面质量。通过超景深电子显微镜对砂轮表面磨粒分布状况进行扫描，计算得到砂轮表面的磨粒密度，建立多颗磨粒随机分布的三维虚拟砂轮模型，将砂轮模型导入到Abaqus有限元仿真软件中进行氮化硅陶瓷的磨削仿真，得到不同参数组合下的磨削力仿真数据。在MK2710的数控磨床上进行氮化硅陶瓷的磨削实验，获取相应的磨削力实验数据，比较实验数值与预测数值，并分析影响磨削力因素的主次顺序。实验数值与预测数值具有一致性，磨削深度对磨削力的影响最大，其次为砂轮转速和径向进给速度。
Abstract:
The paper, aimed at improving the grinding efficiency and surface quality, analyzed the grinding force on Si3N4 ceramics, explored the variation of the grinding force, and predicted the grinding force during the grinding process as well. Super depth of field scanning electron microscope was used for the scanning of abrasive grinding distribution on wheel surface. A three-dimensional model of a plurality of abrasive grinding wheels randomly distributed was established. The wheel model was imported into Abaqus finite element simulation software for grinding simulation. The grinding force value was obtained through the simulation and calculation. From the grinding experiment that the Si3N4 ceramics was processed, the corresponding grinding force data was obtained, the predicted and measured numerical were compared, the primary and secondary order factors that affect the grinding force were analyzed. It proves that the predicted and measured numerical have a good consistency and the order of primary and secondary factors affecting the grinding force are grinding depth, wheel speed and radial feed rate.
