Cutting processes are often the final step within process chains and thus, largely responsible for the surface topography. In addition to design aspects, the surface topography determines the performance and service life of mechanically loaded components. While the surface deviations of 1st, 2nd and 3rd order are largely understood and can be explained by machine and clamping errors, kinematic influences and tool deflection, deficits still remain regarding the surface deviations of 4th order. Similar to the knowledge on surface formation the knowledge on modelling surface deviations of 4th order is limited. However, in order to optimize the design of components and further improve machining processes it is necessary to simulate the surface topography. Therefore, the aim of this project is to increase knowledge on the surface formation in flank milling under special emphasis of the tools microgeometry. Additionally, a novel modelling approach is developed in order to simulate surface deviation of 4th order.

切割工艺通常是工艺链中的最后一步，因此在很大程度上决定了表面形貌。除了设计方面之外，表面形貌还决定机械负载部件的性能和使用寿命。虽然一阶、二阶和三阶表面偏差已被广泛理解，并且可以通过机器和夹紧误差、运动学影响和刀具偏转来解释，但四阶表面偏差仍然存在缺陷。与表面形成的知识类似，四阶表面偏差建模的知识是有限的。然而，为了优化部件设计并进一步改进加工工艺，有必要模拟表面形貌。因此，该项目的目的是在特别强调刀具微观几何形状的情况下增加对侧铣表面形成的了解。此外，还开发了一种新颖的建模方法来模拟四阶表面偏差。
