In highend equipment, the motion system is typically a multiple-input multipleoutput (MIMO) system with multiple degrees of freedom (DOF), and the flexible internal dynamics will produce coupling effects between different motion axes [8,9]. erefore, it is necessary to study the modeling of rigid-flexible, coupled, multi-DOF motion systems.…”

In a multiple degrees of freedom motion system with rigid-flexible coupling, the flexible internal dynamics have a significant negative impact on performance because the degrees of freedom are coupled. Inspired by this problem, a multi-input multioutput state-space model based on modal coordinates is proposed to decouple the rigid body and flexible modes. The closed-loop subspace identification method based on orthogonal is utilized to develop an unbiased standard state-space model. Based on the similarity principle, a modal analysis method is proposed to transfer the standard state-space model to the proposed modal-decomposition-dependent state-space model. Controllability and observability criteria are met to guarantee the minimum realization of the proposed state-space model. Finally, a modeling and modal analysis experiment is conducted on a developed wafer stage of lithographic tool. The results verify the effectiveness and accuracy of the proposed modeling method, as well as the controllability and observability of the proposed model.

“…The approach introduced in this paper builds on solution developed by Montevecchi [13] and generalized by Liao [26] that involves using a single artifact for identification purposes. The generalization consists in formulating the task as a matrix problem so that it is not necessary to simplify the inverse RCSA translation and rotation in the plane X-Z and Y-Z, which leads to the neglect of some cross terms in the compliance matrix as shown below.…”

The Frequency Response Function (FRF) at the tool-tip is important input for machining dynamics prediction, but its measurement is a time-intensive process. The receptance coupling technique offers a faster alternative, suitable for industrial applications where there is experimentally identified receptance matrix at machine-tool holder interface containing enough degrees of freedom to allow connection with various compliant tools modelled using finite element analysis (FEA). The presented approach to the technique further develops simplification of the inverse RCSA by using a single artifact proposed by Montevecchi, presenting simpler and more general mathematical formulation of the receptance matrix identification. The study also looked into how simplifying tool models affects their accuracy and performance in FEA, aiming to find a good balance between detail and efficiency. To prove the proposed technique, thorough tests on two dynamically different machine tools were conducted with various tool geometries.

“…Frequency response function (FRF) of tool tip is often used to demonstrate and suppress the chatter stability [11]. A prediction model of tool tip's frequency response functions was presented and verified by experiment [12]. A model to suppress chatter stability through implementing spindle-tool holder vibration modes was presented by FRF modification [13].…”

To predict chatter stability and suppress chatter vibration, a chatter stability prediction method for the spindle-tool holder-tool system with interface contact characteristics is constructed. A five-DOF model is constructed to determine the spindle-bearing interface dynamic contact stiffness considering the coupling effect of spindle and bearing. A fractal multiscale tool holder-spindle interface dynamic stiffness model is proposed considering time-varying cutting force. The fractal dimensions and cutting force coefficient parameters are identified from the power spectrum experiments and cutting force tests. The cutting force is solved according to the milling stability model. Dynamic model of the spindle-tool holder-tool system is found by the finite element method. Based on extended Floquet theory, chatter stability of the spindle system is studied. Effect of interface parameters, radial cutting depth, and feed rate on milling stability is researched. Milling force tests and milling stability tests are performed in order to verify the reliability of the method. Results find that the increase of front bearing preload and spindle-tool holder’s interference fit are effective to improve the milling stability. The optimal feed rate and the critical radial cutting depth are found. The model proposed in this paper can be used as an instruction for predicting and suppressing the chatter vibration and optimizing cutting parameters and also is helpful for designing the spindle-tool holder-tool system.
