Abstract: A method for masking cooling passages of a turbine component having an external surface, an internal cavity for receiving cooling air, and cooling passages extending therebetween. The location and angle of cooling passages are determined using a robotic arm and a location system. A masking device is placed in the cooling passages located during the locating step. The masking device includes a head portion having a gripping feature for gripping by a robotic arm, and a locating feature for orientation of the masking device by the robotic arm. A retaining portion extending from the head portion is arranged and disposed to retain the masking device in a cooling passage. The retaining portion is narrower proximate a distal end than proximate the head portion. The component and head portion of the masking devices are coated. The masking devices may be removed using the robotic arm and locating system.

Abstract: A process for providing a manufacturing modality for a hybrid article includes defining a model for a build surface on a part in a three dimensional space, and defining a model for an additive structure, the model including an interface surface of the additive structure that corresponds with the build surface in the three dimensional space. The process further includes orienting the x, y and z coordinates of each of the build surface of the part and the interface surface of the model in relation to a three dimensional work space, aligning contours of each of the build surface and the interface surface relative to the work space, and directing a cladding system to define toolpaths for two or more cladding layers that are defined by vertical planar segments or slices of the additive structure model.
