Generating paint gun trajectories for free-form surfaces to satisfy paint thickness requirements is still highly challenging due to the complex geometry of free-from surfaces. In this paper, a CAD-guided paint gun trajectory generation system for free-form surfaces has been developed. A paint thickness verification method is also provided to verify the generated trajectories. The results of experiments and simulations show that the trajectory generation system achieves satisfactory performance. This trajectory generation system can also be applied to generate trajectories for many other CAD-guided robot trajectory planning applications.

Instead of widely used parametric representation of surfaces, a planar facet scheme is used to approximate the painting surfaces. As a result, a new combinatorial gun path planning algorithm is proposed. In this algorithm, big patches are formed by stitching small surfaces together. Therefore, the path planning is solved based on the global characteristics of tire part, and the resulting spray gun paths are well-behaved in the sense of time, coverage, and wastage. The proposed algorithm has been implemented and tested using ROBCADTM /Paint
