Process damping in milling: Theory, experiment, and practical solutions

航空航天结构部件的加工经济性从根本上受到再生颤振和过程阻尼的限制。利用这两种现象将带来巨大的生产率提高和上级竞争优势。例如，最近在谢菲尔德的一个项目能够避免颤振，并将加工时间减少5倍，从而为赞助商赢得了数百万磅的合同。然而，目前对过程阻尼的科学理解是不够的，因此最近的研究已经诉诸于直觉，试错或详尽的实验测试。该项目旨在通过提供新的科学理解和工程工具来克服这些障碍，并将这项技术转移到制造业。

The economics of machining aerospace structural components is fundamentally limited by regenerative chatter and process-damping. Harnessing these two phenomena will lead to enormous productivity gains and superior competitive advantage. For example, a recent project at Sheffield was able to avoid chatter and reduce machining times by a factor of 5, resulting in a multi-million pound contract being awarded to the sponsor. However, current scientific understanding of process-damping is inadequate, so that recent research has resorted to intuition, trial and error, or exhaustive experimental testing. This project aims to overcome these barriers by providing new scientific understanding and engineering tools, and to transfer this technology to the manufacturing community.
