Liang et al combined FEM and MATLAB ® Simulink ® to predict the processing surface of a workpiece, and harmonic response analysis was conducted on the whole machine tool. #Flycut torquer v2 software#In recent years, with the development of computer technology, commercial software is widely used in the dynamic analysis of machine tools, which makes it possible for the holistic modeling of complex and large UFCMTs. Jiang et al applied FEM and structural topology optimization to improve the connection of a simple mechanical structure. Zatarain et al conducted modal analysis of a milling machine by using FEM and showed that the accuracy of the calculation increases as the finite element nodes increase. The finite element method (FEM) has risen to become one of the most commonly used methods of analyzing the performances of machine tools. Hijink and van der Wolf transformed a milling machine tool into a beam model and calculated the natural frequencies with corresponding mode shapes. Gurney and Tobias found that a machine tool can be equated to a damped mass-spring system. Scholars have been studying the dynamic modeling of machine tools for several decades. Thus, in order to improve processing precision, research on the dynamic performances of machine tools is becoming more and more important. However, the tool tip response is mainly responsible for the good or bad surface morphology of a finished workpiece. The surface morphology of UFCMT-machined components can be influenced by a variety of factors, including the machining parameters and the structural dynamics of the machine. An ultra-precision fly cutting machine tool (UFCMT) is one of the key manufacturing machines used to produce ultraprecise components in those industries. To meet the precision and close tolerance requirements of industries such as aerospace, precision instrumentation, and national defense, the quality of manufacturing equipment is continuously being improved. The results elucidated that the tool tip response was significantly affected by ambient vibration, and the isolation foundation had a good effect on vibration isolation. Applying it to the dynamic model, the dynamic response of the tool tip under ambient vibration was investigated. In addition, the power spectrum density estimation method was adopted to simulate the statistical ambient vibration excitation by processing the ambient vibration signal measured over a long period of time. The dynamic model was proven to be valid by comparing the dynamic characteristics of the machine tool obtained by numerical simulation with the experimental results. In particular, the large-span scale flow field mesh model was created and the variation in linear and angular stiffness of journal and thrust bearings with respect to film thickness was investigated by adopting the dynamic mesh technique. In this study, the dynamic model of an UFCMT was established based on the transfer matrix method for multibody systems. The dynamic performances of an ultra-precision fly cutting machine tool (UFCMT) has a dramatic impact on the quality of ultra-precision machining.
