| 摘 要： | 根据工程陶瓷的系统高效深磨试验，研究发现：在高效深磨条件下，磨削氧化锆和氧化铝的材料去除方式不同，分别为塑性成形去除和脆性断裂去除；最大未变形切屑厚度增大至超过临界切深后，其对氧化锆的单颗磨粒法向磨削力的线性增长规律影响很小，而使氧化铝的单颗磨粒法向磨削力的增长趋势逐渐变缓；切向磨削力主要由滑擦和塑性耕犁作用引起的摩擦力组成.

| Abstract: | Based on the experimental results of the high efficiency deep grinding for advanced ceramics,the research indicates that under HEDG grinding condition,PSZ and Al2O3 have different material removal modes:ductile flow or brittle fracture mode.Increase of undeformed chip thickness exceeding the critical grit cutting depth has little effect on the linearity increase disciplinarian of grinding force per grit when grinding PSZ,but makes the grinding force per grit increase in a descending speed when grinding Al2O3.Tangential force are mainly composed of rubbing force caused by sliding and ductile plough between the grain and materials. |
