process demands according to the known conditions
(workpiece model, spray model and robot model, etc.). In
this part the core algorithms of spraying generation process
related directly to practicability of the off-line programming
system should be studied.
Trajectory planning problem of spraying robots is to
determine the best spraying trajectory of spray gun within
the scope of certain constraints based on the known spray
model, the geometry feature of workpiece and the goal of
spraying. This problem can be modeled as the follows.
Given the CAD model of a part M, a workpiece model P,
constraint conditions
