The main function of the off-line trajectory planning and
simulation system for spray painting robot is that based on
the CAD model of a free-form surface, a tool model, the
optimal tool trajectory planner generates an optimal tool
trajectory automatically for a free-form surface for different
workpiece surface, and visually simulates the spraying
trajectory in 3D, and displays spraying results, so as to
optimize spraying effect, improve spraying efficiency and
save costs. Accordingly, the off-line trajectory planning and
simulation system of spray painting robots can be divided
into the following modules: importing and preprocessing of
workpiece model module, spraying process modeling
module, path planning module, trajectory optimization
module and spraying performance simulation module, as
Fig. 1 shows.
