氧化锆陶瓷具有优良的物理和化学性能，在医学、化工、航空航天等领域有着广泛的应用。但是，高硬度和脆性限制了其在制造业中的应用。因此，本工作的目的是开发一种柔性磨料工具的概念的基础上，液体防弹衣的切向磨削力与法向磨削力的大比例，以提高氧化锆陶瓷的表面加工质量。研制了一种柔性仿人体装甲磨具。分析了高剪切低压磨削条件下的基本动力学模拟和微观材料去除过程。为验证柔性仿人体甲磨具的磨削性能，在工业机器人平台上对氧化锆陶瓷工件进行了多组磨削实验。研究了表面粗糙度、表面形貌、磨削力和磨削温度。在最佳磨削条件下，工件的表面粗糙度（Ra）由110 nm降低到9 nm，降低了91.8%。工件表面的划痕消失，并留下均匀的磨削纹理。实验结果表明，研制的柔性仿人体装甲磨具可实现氧化锆陶瓷的超精密磨削。
Zirconia ceramics is widely employed in medical, chemical and aerospace domain due to its excellent combination of physical and chemical attributes. However, high hardness and brittleness property have limited its application in manufacturing industries. Therefore, the present work aimed at development of a flexible abrasive tool based on concept of liquid body armor with large ratio of tangential grinding force to normal grinding force in order to enhance the surface processing quality of zirconia ceramics. A flexible body-armor-like abrasive tool was developed. Fundamental dynamic simulation and micro material removal processing at high-shear and low-pressure grinding conditions was analyzed. A multi-group of grinding experiments were carried out on an industrial robot platform for zirconia ceramic workpieces to validate the grinding performance of flexible body-armor-like abrasive tool. The surface roughness, surface morphology, grinding force and grinding temperature were investigated. At the optimal grinding condition, the surface roughness (Ra) of the workpiece was reduced by 91.8% and decreased from 110 nm to 9 nm. The scratches from the surface of the workpiece vanished and uniform grinding textures were left. The experimental results revealed that the developed flexible body-armor-like abrasive tool could achieve ultra-precision grinding of zirconia ceramics.
