The geometrical qualification of additively manufactured lattice structures has largely focused on the mea- surement of strut diameter, form variations, and surface texture. However, the exterior surfaces of the lattice structure, defined through theoretical supplemental geometry, are critical surfaces that dictate the contact area of the structure on other components within assemblies. Form variations on these surfaces complicate the measurement process by adding ambiguity into what surfaces of the component belong to the controlled ge- ometry. Previous works have developed novel methods to improve data extraction for the measurement of these surfaces using computer aided design (CAD) data for various lattice structures. This work presents an adaptation of these methods to work with additively manufactured (AM) geometries, specifically designing the methodology to account for the form variations between lattice struts. The presented results show the applicability of these methods to AM lattice structures for the measurement of form defined by a theoretical supplemental surface.
增材制造蜂窝结构的几何合格性研究主要集中在测量支撑杆直径、形状变化和表面纹理方面。然而，通过理论补充几何定义的蜂窝结构外表面是关键表面，它们决定了结构在装配中与其他部件接触的面积。这些表面上的形状变化会增加测量过程的复杂性，使难以确定构件的哪些表面属于受控几何范围。此前的研究已开发出多种新方法，利用计算机辅助设计（CAD）数据来改善对各类蜂窝结构这类表面的测量数据提取。本研究将这些方法应用于增材制造（AM）几何结构，并专门设计了能够考虑蜂窝支撑杆之间形状变化的方法。所呈现的结果表明，这些方法适用于增材制造蜂窝结构，可用于测量由理论补充表面定义的形状。 |
