纤维铺放技术是一种复合材料构件自动化制造技术，具有成本低、生产效率高、成品质量高等优点。其中纤维铺放轨迹计算是纤维铺放成型中控制加工路径的关键步骤，直接影响复合材料构件的成型精度和铺放效率。论文基于成熟的商业化CATIA数控加工编程软件进行纤维铺放轨迹计算，获取待处理的加工路径，利用矢量补充和格式转换算法解决了铺放轨迹信息与FANUC机器人兼容性差的问题；借助插值算法求出了输送点和剪断点，补充了铺放轨迹信息，进而得到了完整铺放信息，缩短了开发周期。在基于FANUC机器人的铺放装备上对某飞机舱门进行铺放实验，验证了基于CATIA数控加工技术的纤维铺放轨迹生成方法具有可行性，铺放轨迹结束点位置误差及轨迹间距误差都在±0.5mm之内。

Fiber placement technology is an automated composite manufacturing process, which has many advantages including low cost, high production efficiency, high product quality and so on. As one of the key technologies for the fiber placement, trajectory planning directly influences the placement accuracy and efficiency of composites structure. So far, the domestic fiber placement trajectory planning technology still could not satisfy the need of industrial fiber placement process. To reduce research time of trajectory planning, CATIA CNC machining module is used to generate machining trajectory data in this paper. The machining trajectory information identified by FANUC robot is generated by using vector supplement and format conversion algorithm. By taking advantage of the interpolation algorithm, the delivery points and the cutting points are calculated and composed with the machining trajectory information to achieve the complete fiber placement trajectory information. At last, the fiber placement trajectory information based on CATIA CNC module is tested on the aircraft door placement using the FANUC robot fiber placement equipment, the trajectory end point position error value and the trajectory center distance error value are both controlled within ±0.5mm.
