An method for the rapid manufacturing of aerospace replacement parts 100 is provided, including removing an in-service aerospace part from an aerospace system 120. The present invention further includes placing the in-service aerospace part into a three-dimensional scanning device 130. The invention then scans the in-service aerospace part utilizing the three-dimensional scanning device to develop a three-dimensional scan 140. A computer-aided-design model is then developed based on the three-dimensional scan 150. The invention then direct metal fabricates a replacement aerospace part from the computer-aided-design model utilizing layer-build technology device 170. Finally the replacement aerospace part is installed back into the aerospace system 180.
[0008]FIG. 1 is an illustration of a method for the rapid manufacturing of aerospace replacement parts in accordance with the present invention.
Referring now to FIG. 1, which is an illustration of a method for the rapid manufacturing of aerospace replacement parts 100 in accordance with the present invention. The method includes removing an in-service aerospace part from an aerospace system 120. It is contemplated that the aerospace system 10 can encompass a wide variety of aircraft and military applications. Similarly the in-service aerospace part 12 is intended to encompass any number of components within the aircraft 10. Although a variety of in-service aerospace parts 12 are contemplated, one embodiment contemplates the removal of metal components from the aircraft. The nature of many in-service aerospace parts 12 within an aircraft 10 is such that after continuous use within the aerospace system 10 they can become worn or adapt to their surroundings. Thus the aerospace system 10 as a whole can adjust to the point that parts as originally designed may not fit or properly function. In other circumstances, the in-service aerospace parts 12 may have been modified over the years without correlating changes made to the design specifications. In these, as well as other circumstances, remanufacture of the part to design specifications may be inadequate as well as too costly.
The present invention addresses these scenarios by placing the in-service part within a three-dimensional scanning device 130. A variety of three-dimensional scanning devices 14 are contemplated for use with the present invention. The three-dimensional scanning device 14 may include, but is not limited to, computed-tomography scanners, laser scanners, and touch probe scanners. The thee-dimensional scanning device 14 allows for a complete mapping of the in-service aerospace part 12 removed from the aircraft 10. The invention includes scanning the in-service aerospace part 140. It is contemplated that the results of the scanning device 14 may be raw data or they may take the form of an electronic drawing. Both of these can be referred to as a three-dimensional scan.
The raw data or electronic drawings are then utilized to develop a computer-aided-design model based on the three-dimensional scan 150. It is contemplated the computer-aided design (CAD) model 16 may take on a variety of formats including, but not limited to, formats such as ProE, CATIA, or UniGraphics. Similarly, although the development of a CAD model 16 can be performed on a variety of systems, one embodiment contemplates the use of a workstation 18. An optional step of performing analysis to refine the computer-aided design model 160 may be performed. It is contemplated that the analysis 20 may include and analysis and design modifications necessary to insure the design is suitable for functioning within the aerospace system 10. Traditional engineering and design methodologies are contemplated for use within this analysis. Although the analysis 160 may be performed on the same system or workstation 18 as the CAD model 16 development, it is also contemplated that the analysis 160 may be performed on a remote workstation 20 within the replacement part system network 22.
The present invention therein direct-metal fabricates a replacement aerospace part from the computer-aided-design model utilizing a layer-build technology device 170. Although the layer-build technology device 24 may include a variety of manufacturing devices, one embodiment contemplates the use of a selective laser-sintering device. The selective laser-sintering device is capable of producing metal replacement aerospace parts 26 from the CAD model 16. Although a selective laser-sintering device is preferably, other manufacturing devices such as stereolithography devices. Furthermore, it is contemplated that the step of fabricating from the CAD model 170 is intended to include any intermediary steps such as conversion of the CAD model 16 into a format or file usable by the layer-build technology device 24 such as a sterolithography file.
Finally the present invention includes installation of the replacement aerospace part back into the aircraft 180. The present invention, therefore, allows replacement parts to be replaced without the large inventory costs, excessive tooling costs and time, or non-fit scenarios associated with present methods. This provides a great benefit to aircraft 10 and military applications wherein the small number and uniqueness of in-service parts 12 make their replacement difficult and costly.
