Polishing path planning based on point cloud

Aiming at the problems of high manual labor and low efficiency during the grinding and polishing of curved workpieces, this paper proposes a method for automatically generating a grinding path. The slicing algorithm is used to directly generate the polished path plan for the point cloud data, and streamline it according to the degree of bending of the workpiece area. The characteristics of the point cloud data are better retained and the accuracy of the path planning is improved. The polishing pose was deduced by surface fitting to ensure the uniformity of material removal. Finally, the validity of the method was verified by experiments.
