为了在超精密切割工艺中生产光学质量的部件,拥有高度平衡的系统非常重要。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,这样的模型应该使我们能够预测所需的表面质量的必要的平衡状态,从而节省平衡过程中的时间。在本文中,我们提出了一个模型的超精密切削实验平台,确定振动和位移的平台所造成的不平衡和力的切削过程。实际切削参数由第二模型描述。由于它们依赖于不平衡位移,因此两个模型必须耦合到相互作用模型。为了从振动测量计算平衡重量,采用并提出了用于求解逆问题和不适定问题的正则化技术。
In order to produce components in optical quality in ultra‐precision cutting processes it is very important to have a highly balanced system. Achieving the best possible balancing state is a time consuming process. Therefore, the prediction of the influence of the balancing state on the surface quality of the component is desirable. On the other hand, such a model should enable us to predict a necessary balancing state for a desired surface quality and thus save time in the balancing process. In this paper we present a model of an ultra‐precision cutting experimental platform that determines vibrations and displacements of the platform caused by unbalances and forces from the cutting process. The actual cutting parameters are described by a second model. Since they depend on the unbalance displacements, both models have to be coupled to an interaction model. To compute balancing weights from vibrational measurements, regularization techniques for the solution of inverse and ill‐posed problems are employed and presented.
