摘要
光纤是现代通信技术的重要信息传输载体,而光纤透镜是重要的耦合器件之一。在分析了光纤透镜传统加工技术的基础上,提出了用微磨削技术加工光纤透镜的方法,针对直径125μm的单模光纤,展开了微磨削试验,并结合材料力学理论分析了悬伸长度对成型精度的影响,运用正交法研究了主轴转速、进给速度、磨削深度对表面粗糙度的影响规律。试验结果表明使用该方法能够获得满足精度要求的光纤斜面透镜和锥面透镜,且光纤的悬伸长度与透镜的成型精度呈正相关关系,磨削用量对表面粗糙度有较大影响。
Optical fiber is an important information carrier in modern communication technology, and the fi-ber lens is one of the important coupling devices. Based on the analysis of traditional processing technology of optical fiber lens, the technique of Micro-grinding machining was proposed. Then the multiple sets of ex-periment on single fiber with 125μm diameter were carried, and the influence of overhanging length to the generating precision of the fiber lens was analyzed combined with the material mechanics, the effect law of spindle speed、feed speed and grinding depth that acted on surface roughness was investigated. The results show that the proposed technique can obtain the fiber inclined lens and cone lens which satisfy the require-ment of precision, and that the overhang length and forming precision were positively relationship, and grinding parameters have great influence on surface roughness.
