Abstract:
A method for spraying a coating on an aircraft engine part, the method comprising the steps of:providing an aircraft engine part to receive a coating, wherein the coating is a ceramic material; providing a robotic system comprising a controller and an end effector, the end effector being configured to spray coating material on the aircraft engine part, and the controller having a motion plan and a control program to control operation of the end effector to spray a coat of coating material having a predetermined thickness onto the aircraft engine part; determining a profile of predetermined areas of the aircraft engine part requiring a different thickness of coating; modifying the control program by integrating the profile of the aircraft engine part into the control program to generate a modified control program, wherein the motion plan and modified control program control operation of the end effector to spray a coat of coating material having the predetermined thickness on only the predetermined areas of the aircraft engine part in the profile; completing a pass of the end effector over the aircraft engine part using the motion plan and control program; completing an additional pass of the end effector over the aircraft engine part using the motion plan and the modified control program; and repeating the steps of completing a pass of the end effector and completing an additional pass of the end effector until the desired coating has been sprayed on the aircraft engine part.
