Paint coating thickness uniformity is investigated with a double beta spray gun model to investigate the coating thickness distribution assuming that the robot spraying coating shape is oval. Then, the coating mechanism is analyzed for the spray gun model. The relationship between the coating thickness variation and the coating transfer efficiency is studied experimentally with a uniform gun motion speed. An optimal spray gun motion speed is found with the best results found for a constant ratio of the spray gun speed to the paint transfer efficiency. The experimental results indicate that the speed optimization method effectively improves the coating thickness uniformity.
