To be used in the painting process of wind turbine tower production, the painting performance of a painting robot that can simulate the painting operator movement was examined in comparison with the manually performed painting operation. Dry film thickness (DFT) measurements taken from random painting surfaces and the paint usage amounts related to these values were compared. The same type of painting nozzles were used at the same air pressure and paint temperatures in both manual and robot painting processes, and paint consumption values and DFT values were measured. Measured values showed that in painting operator applications, the deviation from DFT nominal values is 20–22% higher compared to painting robot applications, while the paint consumption value is 15–20% higher.
