Abstract:

     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.

Key words: mechanical manufacture and automation, reverse engineering, blade grinding, industrial robot, path planning
