在高精度切割工艺中，为了生产出光学质量的部件，拥有一个高度平衡的系统是非常重要的。实现最佳的平衡状态是一个耗时的过程。因此，需要预测平衡状态对部件表面质量的影响。另一方面，这样的预测模型应该使我们能够计算出一个客观的必要的平衡状态所需的表面质量，从而节省平衡时间。在这篇文章中，我们提出了一个模型的高精度切割实验平台，描述了平台的振动所造成的不平衡和力的切割过程。为了从振动测量中计算不平衡，我们采用了正则化技术来解决逆问题和不适定问题。版权所有© 2009 by ASME
In high precision cutting processes it is very important to have a highly balanced system in order to produce components in optical quality. Achieving the best possible balancing state is a time consuming process. Therefor the prediction of the influence of the balancing state on the surface quality of the component is desirable. On the other hand such a prediction model should enable us to compute an objective necessary balancing state for a desired surface quality and thus save balancing time. In this article we present a model of an high precision cutting experimental platform that describes vibrations of the platform caused by imbalances and forces from the cutting process. To compute imbalances from vibrational measurements, regularizations techniques for the solution of inverse and ill-posed problems are employed and presented.Copyright © 2009 by ASME
