| Abstract:Aiming at the cumbersome grinding process of the current aeroengine compressor blades and the fact that the path genera?
tion algorithm is generally not adapted to the geometrical shape and processing posture of the compressor blades， a new grinding path
generation algorithm based on the point cloud data of compressor blades and adaptive to the geometrical shape and processing posture of
the compressor blades was proposed. First， obtain the 3D point cloud of the blade by scanning the surface structured light and perform
posture correction， then create a series of appropriately spaced parallel slicing planes in the area of the blade to be machined， and derive
the intersection points between the slicing planes and the point cloud. finally， fit all the intersection points obtained from slicing， and
calculate the path points and cutter orientation of the grinding and polishing path. The results show that by calculating and simulating the
path information of different compressor blades under different postures， it is verified that the proposed algorithm has the characteristics of
adapting to the processing posture and shape of the compressor blades， and the surface reconstruction errors in traditional reverse engineer?
ing can be avoided， which proves the feasibility and effectiveness of the proposed algorithm. It can be further applied to subsequent actual
grinding and polishing operations. |
