基于逆向工程的机器人磨削叶片

Robotic blade grinding based on reverse engineering

提出了一种基于逆向工程的机器人磨削叶片加工方法。机器人逆向工程系统对叶片进行扫描,获得具有叶片型面几何信息的点云数据,利用逆向建模技术生成叶片的逆向CAD模型,并依此采用等距轨迹法进行机器人磨削加工的路径规划,生成机器人加工轨迹。最后,将生成的轨迹应用于机器人叶片磨削系统,试验验证了方法的有效性和可行性。

To solve the problem of automatic blade grinding, a method for robotic blade grinding based on the reverse engineering was proposed. Scanned by a robotic reverse engineering system, the point data with the geometrical information of the blade profile was acquired. A CAD model of the blade was reconstructed by the reverse modeling technique, the isometric trajectory method was employed to proceed the path plan of robotic grinding, and generate the robotic grinding trajectory. The robotic blade grinding experiments were carried out by the generated trajectory to prove the proposed method effective and feasible.
