The presented article offers a comprehensive example of the application of reverse engineering methodologies, specifically employing 3D scanning technology with use of 3D laser scanner in conjunction with advanced CAD software, to support the development and optimization of the protective cabin grid of the forestry machine John Deere 1270E. The primary objective of the process was the reconstruction of the existing structural design in order to generate a digital backup CAD model. The secondary objective was the proposal of design modifications aimed at enhancing the operator’s visibility conditions. A significant methodological innovation consisted in the design and utilization of specialized 3D printed reference bodies - regular dodecahedrons with integrated magnets which effectively addressed challenges associated with precise scanner positioning on ribbed and dark surfaces. Based on operator expertise, the original design was refined by reducing the number of vertical ribs from 16 to 13 and altering their inclination. These modifications resulted in a substantial improvement of the operator’s field of view while maintaining the required protective function. Ergonomic validation was conducted within the Assembly module using a virtual mannequin. To maximize manufacturing efficiency, the vertical rib geometry was standardized, technological locks were integrated, and precise laser marking was implemented. High-strength steel grade S355K2 was selected as the construction material, with laser cutting adopted as the primary fabrication method.

摘要

The presented article offers a comprehensive example of the application of reverse engineering methodologies, specifically employing 3D scanning technology with use of 3D laser scanner in conjunction with advanced CAD software, to support the development and optimization of the protective cabin grid of the forestry machine John Deere 1270E. The primary objective of the process was the reconstruction of the existing structural design in order to generate a digital backup CAD model. The secondary objective was the proposal of design modifications aimed at enhancing the operator’s visibility conditions. A significant methodological innovation consisted in the design and utilization of specialized 3D printed reference bodies - regular dodecahedrons with integrated magnets which effectively addressed challenges associated with precise scanner positioning on ribbed and dark surfaces. Based on operator expertise, the original design was refined by reducing the number of vertical ribs from 16 to 13 and altering their inclination. These modifications resulted in a substantial improvement of the operator’s field of view while maintaining the required protective function.
