Reverse Engineering of Agricultural Machinery Components Using Combined 3D Scanning and Parametric Modeling Technologies

This article proposes a comprehensive methodology for reverse engineering components of agricultural machinery. The methodology uses a mixed approach combining 3D scanning and parametric modeling. The present study is devoted to the use of the Scanform L5 portable laser scanner, which uses laser triangulation to obtain spatial digitization of complex shaped parts with an average accuracy of ± 0.05 mm and a spatial resolution of up to 0.14 mm. Preliminary laboratory studies have confirmed the effectiveness of the scanner in digitizing the external surfaces of agricultural machinery parts for which there is no design documentation. The data obtained from the point cloud is processed using the Geomagic Design X post-processing software and imported into CAD systems, which allows you to create editable solid-state models. This workflow facilitates rapid reproduction, retrofitting, or re-fabrication of key components such as the spray nozzle brackets. The proposed approach is designed to solve such production problems as the need to modernize existing technological equipment, eliminate the shortage of spare parts and technological import substitution. This approach offers a reliable and scalable solution for ensuring operational availability and extending the service life of agricultural machinery.
