随着新的和复杂的表面测量技术的可用性，极高分辨率的形貌和结构测量是可能的。但现在，人们发现，传统的表面参数是不足以提供有关工件的技术功能能力的信息。为了找出适当的参数，用于表征的功能行为，参数化的数学模型的基础上的物理功能的表面是派生。在第二步中，必须定义测量程序和评估算法，以便基于几何测量表面来验证功能能力。提出了一种用面向功能的参数表示曲面的概念。利用这种方法，可以调查因果关系，并将工件的几何和功能特性联系起来。基于这种方法，两个例子，润湿性和摩擦的技术表面，给出。
With the availability of new and sophisticated surface measurement techniques extremely high resolved topography and structure measurements are possible. But now, one detects that conventional surface parameters are insufficient to provide information about the technical functional ability of the workpiece. In order to find out the appropriate parameters for characterising the functional behaviour, a parameterised mathematical model based on physics of the function of the surface is to be derived. In a second step measurement procedures and evaluation algorithm must be defined in order to characterise the functional ability based on the geometrically measured surface. A concept to characterise the surface with function-oriented parameters has been developed. With this method, it is possible to investigate cause-effect relations and to link geometrical and functional properties of workpieces. Based on this approach two examples, wettability and friction of technical surfaces, are given.
