Surface generation during milling considering the tool micro geometry

切割过程通常是工艺链中的最后一步，因此，在很大程度上负责表面形貌。除了设计方面，表面形貌还决定了机械载荷部件的性能和使用寿命。虽然一阶、二阶和三阶的表面偏差在很大程度上可以理解，并且可以用机床和夹紧误差、运动学影响和刀具偏转来解释，但在四阶表面偏差方面仍然存在缺陷。与关于曲面形成的知识类似，关于四阶曲面偏差建模的知识是有限的。然而，为了优化零件的设计和进一步改进加工工艺，有必要对表面形貌进行模拟。因此，这个项目的目的是在特别强调刀具微观几何的情况下，增加侧面铣削表面形成的知识。此外，还提出了一种新的模拟四阶曲面偏差的建模方法。

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.
