“…Sheng (Sheng et al, 2005) converted the CAD model of the object into small triangles and divided them into groups, and planned individual trajectories to approximate the surface of the object. Cai et al (2015aCai et al ( , 2015b proposed that the spraying speed would change when the direction changed during the spraying process by studying the speed history of the tool center point (TCP) of different types of robot trajectories.…”

Purpose This paper aims to present a set of processes for obtaining the global spraying trajectory of a cold spraying robot on a complex surface. Design/methodology/approach The complex workpiece surfaces in the project are first divided by triangular meshing. Then, the geodesic curve method is applied for local path planning. Finally, the subsurface trajectory combination optimization problem is modeled as a GTSP problem and solved by the ant colony algorithm, where the evaluation scores and the uniform design method are used to determine the optimal parameter combination of the algorithm. A global optimized spraying trajectory is thus obtained. Findings The simulation results show that the proposed processes can achieve the shortest global spraying trajectory. Moreover, the cold spraying experiment on the IRB4600 six-joint robot verifies that the spraying trajectory obtained by the processes can ensure a uniform coating thickness. Originality/value The proposed processes address the issue of different parameter combinations, leading to different results when using the ant colony algorithm. The two methods for obtaining the optimal parameter combinations can solve this problem quickly and effectively, and guarantee that the processes obtain the optimal global spraying trajectory.

“…In contemporary manufacturing, robots and handling systems have been developed to control the movement of the spray torch to deposit the coating on substrate surfaces. The macrostructure of the coating is affected by the parameters relevant to the movement, e.g., scanning speed, scanning step, and spray distance [9,10].…”

To solve the problem of paint waste at the boundary of the patch when spraying, a planning method of offset spray path considering boundary of the patch is developed. By analyzing the causes of excessive paint waste at the boundary of the patch, a spray path planning method based on boundary curve of the patch is proposed, and the distance between the spray path and the boundary of the patch is optimized to reduce excessive paint waste. According to the allowable range of the spray height and the error range of the coating thickness, the variable range of the spacing distance is established; on this basis, the equal division method of plane intercept line is used to generate the discrete points of the spray path in the length direction of the patch, and a connection algorithm of the discrete points is used to generate the spray path of the patch. The simulation results show that the method can automatically generate a spray path based on the shape of the patch boundary; under the premise of meeting the uniformity requirements of the coating thickness, paint waste can be effectively reduced during spraying.
