Therefore, current productions are mostly carried out by human workers to adept the delicacy. However, the amount of unabsorbed powders is skill depending, and the clean recycle rate of the powders is scarce, plus, the shape diversity of the workparts and the hard acquirement of skillful workers, together have made the production less economic. This research develops a virtual reality based simulator, in which a virtual counterpart of the painting setup is established and a virtual painting mechanism is built to emulate the spray paint process. The spray gun tool paths are analytically created by the part geometry, and the powder accumulated and unabsorbed rates are digitally calculated along the tool path in the virtual environment to adjust the moving speed and powder discharges. The VR approved tool paths are then be adopted by the production facility. The paths can also be created on-line by intuitive hand operations through visual interaction with a 3D space pointer or haptic device to get realtime approval and skill training.
