An example method that includes receiving, by a computing device, a geometry of the component that includes a plurality of locations on a surface of the component; determining, by the computing device, a respective target thickness of the coating for each respective location of the plurality of locations based on a target coated component geometry and the geometry of the component; and determining, by the computing device, a number of passes or velocity of a coating device for each respective position of a plurality of positions to achieve the respective target thickness for each respective location.

Adaptive control of coating thickness

An example method that includes receiving a first geometry of a component in an uncoated state and a second geometry of the component in a coated state; determining a first difference between the second geometry and a first simulated geometry based on the first geometry and a first spray law comprising a plurality of first spray law parameters; iteratively adjusting at least one first spray law parameter to determine a respective subsequent spray law; iteratively determining a respective subsequent difference between the second geometry and a subsequent simulated geometry based on the first geometry and the subsequent respective spray law; selecting a subsequent spray law from the respective subsequent spray laws based on the respective subsequent differences; and controlling a coating process based on the selected subsequent spray law.

An example method that includes receiving a geometry of a component that includes a plurality of locations on a surface of the component; determining a first target trajectory including a first plurality of target trajectory points and a second target trajectory including a second plurality of target trajectory points, the first and second trajectories offset in a first direction, and the first and second plurality of trajectory points offset in a second direction; determining a respective target coating thickness of the coating based on a target coated component geometry and the geometry; and determining a respective motion vector of a coating device based on the first and second target trajectories to deposit the respective target coating thickness.

An example method that includes receiving a geometry of an uncoated component and a measured coating thickness of a coated test; determining a simulated coating thickness based on the geometry and a first spray law including a plurality of first spray law parameters; determining a difference between the simulated coating thicknesses and the measured coating thickness; iteratively adjusting at least one first spray law parameter to determine a respective subsequent spray law and determining a respective subsequent difference between the measured coating thickness and a subsequent simulated coating thickness based on the geometry and the respective subsequent spray law; selecting a subsequent spray law from the plurality of respective subsequent spray laws based on the respective subsequent differences; and controlling a coating process based on the selected subsequent spray law to compensate for the difference.
