“…-lack of guarantee of high accuracy (up to ±0.5 mm) of details of complex geometry; -the need to create a 3D model from a portrait in the «*.stl» file format when manufacturing a part on CNC machines, which is dictated by the requirements of its software; -impossibility of creating design, technological and operational documentation from portrait data. There are a large number of methods and algorithms of reverse engineering based on reverse engineering, which are developed for the specific requirements of the researched tasks [17,18]. This is the high accuracy of surface reproduction, or the reproduction of complex structures, or their many dimensions, or, conversely, the possibility of replacing them with geometric primitives [19].…”

The subject of the study is sustainable reverse engineering and conventional reverse engineering of aviation equipment (AE) samples. The object of the study is the geometric accuracy of the extracted portrait of a part of a complex shape in comparison with the constructed analytical standard (AS). The work is aimed at researching the methods of sustainable reverse engineering and conventional reverse engineering on the example of the digitization of the box of the AE steering machine, chosen as a part of a complex shape. For this, a portrait of the "*.stl" and AS format file was created and compared by performing a control operation with the determination of the time spent. A structural and technological analysis of the box of the AE steering machine was carried out, which showed that the box has through holes of various diameters (from 10 to 41.6 mm) and shapes (square, trapezoidal, round); thin walls between holes (up to 1.6 mm); right angles and their rounding radii (up to 1–4 mm); the thickness of the body walls is 2.4 mm, etc. 3D scanner – ARTEC SPACE SPIDER (Luxembourg) was selected and scanning was performed. According to the analysis of research methods of reverse engineering, it was established that the use of permanent and conventional reverse engineering allows, in the first case, to quickly manufacture a part by 3D printing or milling on CNC machines, and in the second case, to create its AS with the provision of the specified geometric accuracy. The difference in time between permanent and normal reverse engineering was 8 hours in favor of the former. Control of the ideal portrait according to the AS of the AE steering machine body showed the maximum deviations from –0.30 mm to +0.23 mm and the minimum deviations from –0.04 mm to +0.08 mm. The smallest indicators were observed on vertical and horizontal planes, and the largest - in cities with plane slopes, corners and small radii. This made it possible to establish that the existing capabilities of the Geomagic Design X software for correcting the received portrait of the "*.stl" format file currently do not guarantee the provision of geometric accuracy requirements (up to ±0.5 mm) for the manufacture of an experimental part of a complex shape – the AE steering machine body with 3D printing. The resulting ideal portrait can be used to manufacture a part by milling on CNC machines, taking into account deviations at the stage of process model formation, which can become the topic of further research.

“…Control is implemented after the stages of transformation of the portrait from *.stl to a 3D model in the SolidWorks software, and back to *.stl in the Geomagic Control X package, followed by its comparison with the *.х_т analytical reference of the keel. Exporting the files based on *.stl in CAD systems made it possible to preserve the geometry and shape while the results of control were considered reliable and adequate compared to the data reported in [11].…”

“…The authors of [10] attempt to explain the process of reengineering involving neural networks and give a model for the use of this technique industrially; however, that is not confirmed by practical introduction and implementation. Work [11] reports the results of reengineering for 3D modeling of the turboprop rotor blade and shows that importing and exporting files in CAD systems sometimes results in loss of geometric information. Study [12] gives a model of an expert system in the reengineering of technological equipment in the processing industry using artificial intelligence, decision-support systems, etc.…”

The subject of this research is the technology of reengineering and control of parts of aircraft objects (AOs) and technological equipment for their manufacture. The predefined accuracy of the keel of a light aircraft and molding surfaces of technological equipment for its manufacture has been ensured by using reengineering technology and CAD systems. A portrait of the actual physically existing keel of a light aircraft was built in the *.stl file format using the software Artec Studio (USA). The control and comparison of the geometry of the shapes of the analytical standard with the actual physically existing keel of a light aircraft based on its portrait have been implemented. The methods used are the analysis and synthesis of the experimental geometry of shapes, the method of expert evaluations. The following results were obtained: based on the analysis and synthesis, the presence of significant errors in the accuracy of the manufacture of the keel for a light aircraft in the range from −5.26 mm to +5.39 mm was detected. It has been shown that the key factor is the keel's relative plane indicator, which is outside the tolerance margin and is 85 %. It was decided to fabricate new technological equipment from another material – organic plastics. Control of the technological equipment made from organic plastics for the keel of a light aircraft showed that the shape-forming surfaces of the equipment have appropriate shapes and sizes corresponding to the existing analytical standard and are devoid of inaccuracies that occurred in the previous version. The range of keel margins that was made using the new technological equipment from organic plastics is from –0.51 mm to +0.34 mm while the relative plane of the keel outside the tolerance margin does not exceed 15 %. The study results showed the adequacy of the decisions taken, ensuring the predefined accuracy for the keel of a light aircraft and molding surfaces of technological equipment for its manufacture.
