加工复合材料零件是一个具有挑战性的制造过程。这些复合材料零件中的许多不仅具有非常大的尺寸，而且还缺乏明确的位置特征。通常，这些复合材料零件的周边分布有需要修整的毛刺。配备磨料水射流（AWJ）的工业机器人已被证明是一种有效的方法来修剪复合材料零件。针对AWJ机器人对无明确定位特征的大尺寸复合材料零件进行修边的问题，提出了一种解决方法。在AWJ机器人的末端执行器上绑定标准块，作为定位基准。然后，通过移动AWJ机器人，使得该标准块位于选定区域附近，用便携式激光扫描仪沿着该标准块扫描选定区域。在标准块的帮助下，为每个区域生成的点云建立局部坐标系。通过坐标系转换，将这几个区域的点云构建成一个完整的点云系统。因此，无需使用大批量磁贴，即可获得大尺寸零件的点云系统。最后，通过点云系统与预期最终产品的三维模型的匹配，预期最终产品的三维模型被用来生成刀具切削路径与一个特殊的三维CAM程序。利用该方法，可以对没有明确定位特征的大型复合材料零件进行切边。
Machining composite parts is a challenging manufacturing process. Many of these composite parts are not only with very large sizes but also lack of well-defined location characteristics. And usually, these composite parts are with burrs distributed on the periphery that require trimming. An industrial robot equipped with an abrasive water jet (AWJ) has been proved to be an effective method for trimming composite parts. This article proposed a method to solve the problem of trimming large-size composite parts without well-defined location characteristics with an AWJ robot. A standard block is bound on the end effector of the AWJ robot, as a locating reference. Then, by moving the AWJ robot so that this standard block is at the proximity of selected regions, the selected regions, along with this standard block, are scanned with a portable laser scanner. With the help of the standard block, a local coordinate system is established for the point cloud generated at each region. And further, the point clouds of these several regions are constructed into an integrated point cloud system through coordinate system transformation. Therefore, without using a large batch of magnetic stickers, a point cloud system of the large-size part is obtained. Finally, by matching the point cloud system with the 3D model of the expected final product, the 3D model of the expected final product is used to generate the tool cutting path with a special 3D CAM program. With this method, trimming large-size composite parts without well-defined location characteristics becomes realistic.
