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.

加工航空航天结构部件的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力提升和卓越的竞争优势。例如，谢菲尔德最近的一个项目能够避免颤振并将加工时间减少 5 倍，从而使赞助商获得了数百万英镑的合同。然而，目前对过程阻尼的科学理解还不够，因此最近的研究诉诸于直觉、反复试验或详尽的实验测试。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，并将该技术转移到制造界。
