Structure-oriented analysis and modeling of microtopography of engineering surfaces for process description and analysis (SAMMTOP)

尽管表面通常用简单的标准化粗糙度参数(如Ra或Rz)来表征，一方面是为了总结制造过程的状态，另一方面是为了预测工件的功能特性，但它们描述功能特性的能力有限。由于计算过程和随之而来的信息损失，不可能总是能够比较不同的制造过程，或者更确切地说，对结果的解释通常只有在关于恒定和相对稳定的制造过程的先验知识的情况下才有意义。因此，在拟议的项目中，开发了一种不基于粗糙度参数的制造过程评估的替代方法。在这样做的过程中，第一次广泛研究了轮廓测量环境中面向结构的评估，以便建立表面形貌和制造过程状态之间的一般关系。

Although surfaces are typically characterized with simple standardized roughness parameters (like e.g. Ra or Rz), to conclude on the state of the manufacturing process on the one hand and to predict the functional characteristics of the workpiece on the other hand, they have limited capabilities to describe the functional characteristics. Due to the calculation procedure and the accompanying loss of information, it is not always possible to compare different manufacturing processes or rather an interpretation of the results is often only meaningful with a priori knowledge about a constant and relatively stable manufacturing process. Thus, in the proposed project an alternative approach for the assessment of manufacturing processes is developed that is not based on roughness parameters. In doing so, a structure-oriented evaluation in the profile measurement context is extensively examined for the first time in order to establish general relations between the surface topography and the state of the manufacturing process.
