The Influence of Spraying Angle on Robotic Trajectory Planning

摘要

The influence of roll angle on coating uniformity is analyzed by establishing the formula between the average film thickness and it. The functional relations of coating uniformity to yaw angle and roll angle are obtained by measuring the average film thickness under the diferrent angles. The minor changes of spray angle have little influence on coating uniformity, and the tracking error of robotic spray gun is very small, therefore it can be ignored when studying robotic trajectory planning. The alteration of spraying angle, spraying distance and moving speed of spray gun can lead to the change of coating thickness, so optimized combination of them can improve coating uniformity.
