Actuator alignment is crucial and of paramount importance in meeting high precision pointing and reliable control performance of Aerospace vehicle emission requirements. In this paper, a holistic approach has been made for precise alignment of the Aerospace control surfaces with the actuators through the development of an Assembly Fixture with the help of CAD software taking into account variations in fabrication and assembly for meeting the stringent specification requirements. The Assembly Fixture resulted in reduction of lead time for 3D inspection and also ensured repeatable functional performance of the actuator assembly.
