Ultra-precision engineering has at its core the size, shape and texture of the components used. This study examines how the relationship between them and their role is changing with respect to manufacture, function and characterization, with particular emphasis on aspects of miniaturization and ultra-precision engineering. Surface geometry has traditionally been linked to the generation of part size. This is changing: the study shows that it is now possible to separate shape and texture from the size generation and to design them independently for function. In addition, with miniaturization, the roles and properties of shape and texture that affect performance change considerably, especially those tribological functions involving contact and flow. This study reveals these changes and shows how the characterization of the surfaces making up a surface system can take these into account.
超精密工程的核心是所使用的组件的尺寸、形状和纹理。本研究考察了它们之间的关系及其在制造、功能和特性方面的作用如何随着微型化和超精密工程的发展而变化，特别强调了微型化的各个方面。传统上，表面几何形状与零件尺寸的生成有关。这种情况正在发生变化：研究表明，现在可以将形状和纹理从尺寸生成中分离出来，并为功能独立设计它们。此外，随着微型化，影响性能的形状和纹理的作用和特性会发生很大变化，特别是涉及接触和流动的摩擦学功能。本研究揭示了这些变化，并展示了如何考虑构成表面系统的表面的特性。
