The present disclosure relates to systems and methods related to aircraft component repair processes, more specifically, systems and methods for vacuum furnace post-processing.
Vacuum furnaces may often be used in repair processes for aerospace components and assemblies, such as brazing, heat treatment vacuum cleaning, annealing, and sintering. Components to be process may be loaded into baskets, and stacked in the furnace to maximize loading capacity prior to the repair process. After the repair process within a respective vacuum furnace, the baskets may be removed from the furnace and inspected. Information regarding location and placement of the respective components and baskets may be lost after removal from the vacuum furnace.
A method of generating a loaded layout in a vacuum furnace corresponding to an actual layout in the vacuum furnace during operation of the vacuum furnace is disclosed herein. The method may comprise: receiving, via a processor, a visual data of a loading process of the vacuum furnace from a camera; comparing, via the processor, the visual data to a predetermined maximum capacity layout for the vacuum furnace; and arranging, via the processor, the visual data into the loaded layout in response to comparing the visual data.
In various embodiments, the method may further comprise sending, via the processor, the loaded layout to a display device. The method may further comprise storing, via the processor, the loaded layout for a batch load in the furnace for at least one of traceability, root cause analysis, or quality investigations. The visual data may include a visual image for each row of components disposed in the vacuum furnace, and the loaded layout displayed on the display device may include the visual image for each row corresponding a respective location a component in the visual image was in the vacuum furnace. The visual data may be video data. The loaded layout may include a two-dimensional image. The loaded layout may include a three-dimensional image.
A method is disclosed herein. The method may comprise: capturing a visual data of a vacuum furnace loading process, the visual data including a first image of a first row of components disposed on a loading stand and a second image of a second row of components disposed on the loading stand in the vacuum furnace, the loading stand configured to be placed in a vacuum furnace; and arranging the first image and the second image into a layout image, the layout image including the first image, the second image, and location indicators, the location indicators corresponding to a position of components within the vacuum furnace during operation of the vacuum furnace.
In various embodiments, capturing the visual data may be captured via a camera. The visual data may be video data. The first image and the second image may be captured as still images. The layout image may be a three-dimensional image. The first row of components may include a first basket with a first set of components and a second basket with a second set of components. The first set of components may be different from the second set of components.
A control system for vacuum furnace post processing is disclosed herein. The control system may comprise: a camera configured to be disposed with a line of sight to a loading stand; a controller configured to operably couple to the camera, the controller configured to: receive, through the camera, visual data corresponding to a loading process of a plurality of baskets on the loading stand, each basket in the plurality of baskets having a component disposed therein; and arrange the visual data into a loaded layout, the loaded layout corresponding to an actual layout of the plurality of baskets during after the loading process.
In various embodiments, the controller may be further configured to compare the visual data to a predetermined maximum capacity layout prior to arranging the visual data. Arranging the visual data into the loaded layout may be in response to comparing the visual data to the predetermined maximum capacity layout.

Disclosed herein are systems and methods for vacuum furnace post-processing. In particular, the system may include a controller in operable communication with a camera. A “camera” as disclosed herein refers to a device for recording visual images in the forms of photographs, film or video signals. In various embodiments, a lens of the camera is aligned into a vacuum furnace for an aircraft repair process (i.e., brazing, heat treatment, vacuum cleaning, annealing, sintering, etc.). In various embodiments, the controller is configured to receive visual data from the camera. In various embodiments, visual data may correspond to various images captured during a loading process (i.e., loading a plurality of components into the vacuum furnace). In various embodiments, the controller is further configured to arrange the visual data captured and match the visual data to an arrangement of the plurality of components within the vacuum furnace after loading. In other words, the controller may arrange the visual data and send an arranged image to a display device. In various embodiments, the arranged image may correspond to a 2-dimensional image (2-D) or a 3-dimensional (3-D) image of the plurality of components as they were loaded in the vacuum furnace. In various embodiments, the 2-D or 3-D output by the controller may comprise a loaded layout within the furnace. In this regard, whether a component was disposed proximate a front, rear, bottom, top, or middle of the vacuum furnace may be determined from the loaded layout.
In various embodiments, the systems and methods disclosed herein may provide visual records of components loaded within a vacuum furnace, in accordance with various embodiments. In various embodiments, the loaded layout may allow visualization and referencing of a position in which components or baskets are loaded in the vacuum furnace. In various embodiments, the systems and methods may further allow better traceability during post-processing root cause analysis, quality investigations or the like.
