Robot grinding optimization method based on polynomial interpolation

The high-efficiency robotic edge grinding technology for precision forged blades of aero engines can significantly improve the blade machining quality, enhance the engine performance stability, reduce rework and additional maintenance, and reduce the overall operating and maintenance costs. Therefore, the robotic edge grinding technology of precision forged blades of aero engines is investigated in this paper. Firstly, based on the characteristics of the robot, the robot dynamics model is established by the D-H method. On this basis, based on polynomial interpolation, inverse kinematics solution, precise control of edge grinding trajectory. Finally, an example is given to verify the process of a certain type of engine blade. The results show that the proposed method is reasonable and effective, and the efficiency of blade machining is improved.
