Abstract
In certain embodiments, a system comprises a robot, a spray gun coupled to the robot and operable to spray a first predefined number of passes of a material onto a substrate at a first flow rate, and a measurement device operable to measure one or more properties of the material sprayed onto the substrate while the material is wet. The system further comprises an analyzer operable to determine a thickness of the wet material based on the one or more measured properties and calculate a second flow rate required to achieve a cured thickness of the material within a second predefined number of passes. The calculated second flow rate is based on the first predefined number of passes, an expected thickness of the wet material for one pass of the first predefined number of passes, the determined thickness of the wet material, and the first flow rate.
