摘要

摘要: 实现了一种对大型复杂曲面透明件的非接触在线测量和建模方法，该方法能够适应航空座舱透明件刚度低、表面易划伤的结构特点。基于五轴数控加工中心，利用光谱共焦位移传感器和数据采集卡，在线记录运行过程中工件表面和机床各轴的位置坐标，对采集的两组数据进行矢量求和，并通过开发软件进行处理，实现了透明件的非接触测量与数学模型的重建。通过实验完成了曲面点云的采集、数据处理以及曲面模型的重构，验证了方法的可行性。

Abstract: Non-contact in-line measurement and modeling methods were carried out for the transparency with large complex surface, which was suitable for the aeronautical transparencies with low toughness and scratch resistance. For the numerical control machine, the spectral confocal displacement sensor and data acquisition card to record the position coordinates of the workpiece surface were used, and the machine axes in the running process. The non-contact measurement and reconstruction model method of transparent parts were carried out by using the vector sums the two sets of data collected and the software development. The acquisition of surface point cloud, data processing and reconstruction model for surface were completed with the experiments, and the feasibility of the method was verified.
