Reverse engineering can be considered as the methodological process of analyzing and reconstructing a digital model of a physical asset. It has gained considerable interest with the advent of sophisticated sensors and data processing technologies hence becoming an important enabler for the product digital twin. However, while existing approaches to reverse engineering focus on the mere geometric reconstruction, this paper presents a novel paradigm called function-oriented surface reconstruction, that is capable of reconstructing the underlying part and surface function and thus outperforms existing methods. The applicability of the presented method is demonstrated through a case study of a gearbox.

逆向工程可以被视为分析和重建物理资产数字模型的方法论过程。随着复杂传感器和数据处理技术的出现，它引起了极大的兴趣，因此成为产品数字孪生的重要推动者。然而，虽然现有的逆向工程方法只关注几何重建，但本文提出了一种称为面向功能的表面重建的新范式，它能够重建底层部分和表面功能，从而优于现有方法。通过齿轮箱的案例研究证明了所提出方法的适用性。
