摘　　要：为了了解有序化砂轮磨削钛合金的表面质量,将叶序理论引入到CBN电镀砂轮磨粒的设计当中来,采用紫外线感光干膜作为掩膜感光层来实现在砂轮表面磨粒的排布,利用光刻技术和复合电镀工艺技术制造出磨粒有序排布外圆砂轮,并对钛合金TC4进行磨削实验研究,获得了不同的进给速度及磨削深度对磨粒叶序排布,错位排布,无序排布砂轮磨削表面粗糙度的影响规律.实验结果表明:在相同的磨削条件下,与其它排布砂轮相比,磨粒叶序排布砂轮磨削工件表面得到的粗糙度值最小。In order to understand the surface quality of the grinding wheel during grinding TC4 with engineered grinding wheel, phyllotactic pattern theory is introduced into the design of the electroplating CBN grinding wheel and use UV photography as mask to realize abrasive controllable configuration on the surface of grinding wheel. The engineered grinding wheels is fabricated using UV lithography method and electroplating technology. The titanium alloy TC4 was experimented with the grinding and obtain the influence of surface roughness with random, phyllotactic and staggered configuration ranging with the feed speed and the grinding depth. The results show that under the same experiment conditions, the grinding surface roughness values with phyllotactic configuration is less than other configuration.
