精密机床是制造高质量微尺寸产品或微尺寸特征的基本要素，它们直接影响加工精度，可重复性和效率。关于构成工业机床的部件的设计，有大量文献。然而，很少有人从动力学的角度系统地解决精密机床的设计问题。在本文中，与精密机床的设计，特别强调被放置在动态方面的主要因素，影响精密机床的性能和加工过程中的问题。简要回顾了精密机床的设计原则，重点是加工动力学。然后，精密机床的设计过程和实用的建模和仿真方法进行了讨论。以快速刀具伺服系统和五轴台式微铣床为例进行了设计和分析。在两个案例研究中使用的设计和分析，制定建议的设计方法和准则的基础上。
Precision machine tools are essential elements in the fabrication of high-quality micro-sized products or micro-sized features and they directly affect the machining accuracy, repeatability, and efficiency. There is a significant literature on the design of the components that constitute an industrial machine tool. However, little effort has been expended on systematically addressing the design of precision machine tools from a dynamics point of view. In this paper, the issues associated with the design of precision machine tools are presented with particular emphasis being placed on dynamic aspects as the major factors that affect the performance of the precision machine tool and the machining processes. A brief review of the design principles of precision machine tools with an emphasis on machining dynamics is presented. Then, the design processes of precision machine tools and practical modelling and simulation approaches are discussed. Case studies on the design and analysis of a fast tool servo system and a five-axis bench-top micro-milling machine are reported. The design and analysis used in the two case studies are formulated based on the proposed design methodology and guidelines.
