摘要：The spray coating process in ship-building is strongly affecting the ship's lifetime. However, skill transfer of the coating operation to beginner learn by watching senior worker's coating work. To improve such a situation, we developed a training program for spray coating workers. The program consists of practical training and theoretical training and provides a systematic approach to the skill transfer. The practical training employs a 3D virtual reality (VR) spray coating simulator. The practical training is conducted safely by using the simulator. In addition, the simulator has functions to enhance the education effect such as a visualization of spray gun motion. We executed the training program actually and evaluated its effect quantitatively. By comparing the spray coating skill before and after the training, the education effect was validated. Also from an analysis of data obtained from the training, we found there is a strong correlation between spray gun-to-target distance and distribution of paint film thickness.
