  • In order to solve the problem of poor coating uniformity of composite conical surfaces in tool trajectory optimization, a spray tool trajectory generation method was proposed according to the geometrical characteristics of conical surfaces. Using the spray trajectory optimization method that is based on the 3D model of a spray tool for conical surfaces, the tool trajectory optimization at the junction of the combined conical surfaces was discussed. Then, optimal objective functions were established to optimize the spray parameters. Simulation results show that the coating thickness after optimization meets the coating requirement. Compared with the general method, the proposed method can reduce the error of coating thickness between the maximal and ideal values by 0.4 m, and reduce the error between the minimal and ideal values by 1.0 m. In addition, the above errors are 0.8 and 1.4 m less in combination of synclastic patches than those in combination of inverted patches.
