Aplicación de la ingeniería inversa en obtener la geometría del sistema cono y corona para la generación del código ISO y su modelamiento de manufactura aplicado a vehículos pick up

Abstract

The objective of this research project was to apply reverse engineering to the cone-crown system through 3D simulation to obtain its geometry, the generation of the ISO code, and its manufacturing processes. Two cone-crown sets were used: D-MAX 3.0 Diesel 4X2 and Wingle 5 2.2 CD 4X2, with a ratio transmission of 45:11 and 41:10, respectively. The scanning technique to be used was determined, followed by post-processing of the scan that optimizes the quality of the model so that it is suitable for export to CAD software. A reconstruction process was carried out using various techniques. The generated model was validated through a comparison method with the real object. Subsequently, each computerized model was evaluated through a finite element simulation process including three configurations of the inclination angle of the teeth: original, 18º-18º, and 14.5º-14.5º. Where the efforts, deformations, safety factors, and the life cycle of the material under working conditions were analyzed. In addition, the validated models were exported to CAM software to execute roughing, semi-finishing, and finishing machining processes followed by the generation of ISO codes. The results showed that through the photogrammetric scanning process, it was possible to obtain CAD models with an approximation of 95% to the real pieces so that the digital models can be accepted without risking the design of the piece to carry out its analysis through computational simulation. It is concluded through the finite elements that the original configuration of the cone-crown system is the most optimal, indicating that the selected material is adequate to take it to a CAM process. It is recommended to clean the objects to be worked on before carrying out the 3D scan. In addition, the parts to be scanned must have an opaque incidence surface.
