Abstract: Aiming at the problems of the complex blades of robotic belt grinding, the tool path planning and post processing techniques were studied, which were used in the profile, intake and exhaust sides of the complex blades. After the analysis of the computational efficiency and machining efficiency for the complex surfaces of robotic belt grinding path planning, the method was purposed to put the line spacing in Cartesian space based on the residual height into the parametric line spacing, and the data of the central coordinates position, supporting axial vector and axial vector of the contact wheel was post processed into the pose information of robot. The actual processing tests were carried out on the platform of the robotic belt grinding equipment. The results indicate that the tool path planning and post processing method can effectively solve the complex problem of grinding the surface of the complex blades, and can also possess the characteristics of less machining path length and the total number, with a simple calculation, high efficiency, high precision machining.
