为了满足对由各种材料制成的高质量微型零件日益增长的需求，电子、生物医学和光学工业正朝着微/纳米加工的方向发展。目前，机械微加工只能在非常低的进给速度和小的切削深度下进行，很难达到合理的生产率。为解决高精度模具或微细零件微纳加工生产率低的问题，设计开发了高精度、高效率的微纳加工中心。所研制的机床配有反平衡轴，每根轴在其重心处驱动，实现高加减速而不产生任何振动。本文介绍了该机床及其控制测量系统设计的理论背景和实践背景。然后，对所设计机床的加工性能进行了试验评价。
In order to meet the increasing demand for high-quality miniature parts made of a wide variety of materials, the electronics, biomedical and optical industries are moving towards micro/nano-machining. Currently, mechanical micromachining can only be performed under very low feed rates and small depth of cut, which makes it very difficult to reach reasonable productivity. To cope with the low-productivity problem for micro/nano-machining of high-precision molds or miniature parts, a highly accurate and productive machining center has been designed and developed in this paper. The developed machine tool is equipped with counter balance axes, and each axis is driven at its center of gravity to achieve high acceleration/deceleration without causing any vibration. This paper describes the theoretical and practical background of the design of the machine tool and its control and measurement system. Then, experiments are carried out to evaluate the machining performance of this designed machine tool.
