为了使用微铣削工艺实现精确加工，需要使用精密刀具（直径范围为0.2 mm-2 mm）。由于微细铣削刀具及其相关机床结构的特殊性，将宏观铣削过程中的经典技术（如仅考虑刀具/工件动力学的稳定性预测）直接用于微细铣削过程的分析是不够的。事实证明，还需要考虑整个机器结构的特性。因此，有必要对微铣床结构进行机械振动研究，并将其作为多体系统进行建模。采用经典模态分析方法识别了一种微型铣床结构的固有频率，并通过对比实验测试中加工工件的表面粗糙度来验证结构的影响。（© 2009 Wiley‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
To achieve accurate machining using the micro milling process, precise tools (diameter range 0.2 mm–2 mm) are used. Because of the special properties of the micro milling tools and the related machine structures, it is not enough to assign the classical technique in macro milling process, e.g. stability prediction respecting only the dynamics of the tool/workpiece, directly to analyze the micro milling process. It is proved to be required also to take characteristics of the entire machine structure into account. Therefore, the mechanical vibration research of the micro milling machine structure is necessary, and subsequently the modeling of the structure as a multiple body system is described. The identification of the natural frequencies of a micro milling machine structure by means of the classical modal analysis is shown, and the influence of the structure is verified by comparing the surface roughness of the manufactured workpiece in experimental testings.
