Precision Analysis of Chain Wheel Geometry Reconstruction Based on Contact and Optical Measurement Data

Abstract

This study focuses on the detailed reconstruction of chain wheel geometry utilizing measurement data gathered from the MarSurfXC20 contact system and the iNEXIVE VMA 2520 optical system. Supplementary data were also gathered from a digital micrometer and a caliper to provide a comprehensive data set for the analyzed geometry. The geometric model of the chain wheel was then constructed using Siemens NX software. The reconstructed model was subsequently compared with the original design specifications to assess the fidelity of the reconstructed model. Results demonstrate a high degree of correlation between the model generated by reverse engineering and the original design model. Despite the satisfactory correlation, potential inaccuracies were identified, necessitating further research to mitigate these discrepancies and optimize the procedures for parameters beyond the established tolerance. The study affirms the feasibility of utilizing contact and optical measuring systems in the reverse engineering process of chain wheel geometry, although it underscores the need for additional refinement to improve the model's accuracy.

“…Reverse engineering (RE) encompasses a broad spectrum of methods employed to transmute real objects into a virtual realm [1][2][3]. Central to this discipline are tasks encompassing data acquisition, geometric reconstruction, and the transformation of this data into a format amenable to Computer-Aided Design (CAD) systems.…”
