Abstract (English): |
To address the challenges of high grinding force and poor processing quality in grinding zirconia ceramics with traditional grinding wheels, this study explores the use of leaf vein bionic fractal textured diamond grinding wheels. These wheels, designed with fractal angles of 30.0°, 45.0°, and 60.0°, leverage the leaf vein bionic fractal texture's capabilities in reducing drag, guiding flow, heat dissipation, and mass transfer. The effects of the original grinding wheel and the three types of bionic fractal grinding wheels on the surface roughness (Ra), grinding force, and grinding force ratio of zirconia ceramics were compared and analyzed. The results show that the bionic fractal grinding wheels outperform the original grinding wheel. Specifically, compared to the original grinding wheel, the normal grinding force of the bionic fractal grinding wheel is reduced by 12.7% to 55.8%, and the tangential grinding force is reduced by 8.1% to 40.3%. The bionic fractal grinding wheels have not obvious effects on the surface roughness Ra. When the fractal angle is 30.0°, the minimum grinding force ratio is 1.4 to 3.0, and the minimum surface roughness Ra is 1.824 μm. [ABSTRACT FROM AUTHOR] |

针对氧化锆陶瓷在传统砂轮磨削过程中存在的磨削力大、加工质量较差等问题, 根据叶脉分形结构 在减阻导流与散热传质方面的优异性能, 建立叶脉分形角模型, 设计 30.0°、45.0°和 60.0° 3 种不同分形角度 的叶脉仿生分形纹理化金刚石砂轮, 对比分析原始砂轮与 3 种仿生分形砂轮对氧化锆陶瓷磨削表面粗糙度 Ra、磨削力和磨削力比的影响。结果表明:仿生分形砂轮比原始砂轮具有更好的磨削性能; 与原始砂轮相比, 仿生分形砂轮的法向磨削力降低了 12.7%~55.8%, 切向磨削力降低了 8.1%~40.3%, 且其对表面粗糙度 Ra 影响不明显; 当分形角为 30.0°时, 获得的磨削力比最小值为 1.4~3.0, 表面粗糙度 Ra 最小值为 1.824 μm。 [ABSTRACT FROM AUTHOR] |
