The cutting vibration is one of the main factors to affect precision machining. In this paper, the influence of tool rake angle on cutting vibration is studied at different cutting speed in turning operation, and corresponding theoretical analysis is made. The experiment results show that: the amplitude of machining vibration gradually decreases with tool rake angle increasing; while rake angle o g <0°, the biggest amplitude occurs at V=50~70m/min; While o g ≥0°, it is at V=160~180m/min. Moreover, theory and experiment foundation is presented on avoiding the biggest amplitude range so as to guarantee quality of precision machining at high speed.

“…The unique analytical formula, FE simulation, and experimental verification of outside-diameter grooving with an uncoated carbide tool establish the mean friction coefficient m used in the FE model in the HSM [40]. In recent years, multiscale FEM has become a popular and useful model for analyzing the non-linear behavior of structures [41][42][43][44][45] which has high modeling and solution efficiency. In multiscale FEM, a large number of solid elements are replaced by shell or beam elements.…”

The high-precision machine tool's dynamic, static, and rigid nature directly affects the machining efficiency and surface quality. Static and dynamic analyses are essential for the design and improvement of precision machine tools to ensure good tool performance under difficult and demanding machining conditions. In this study, the performance of a high-precision machine tool was analyzed using its virtual model created using SOLIDWORKS. Static and model analysis using ANSYS Workbench software was conducted to establish the tool's static deformation and static stiffness. Furthermore, the static and dynamic characteristics of the tool were explored using a ﬁnite element modeling approach to study their performance. In particular, the structure, static force, modal, frequency spectrum, and topology optimization of machine tools were primarily analyzed. Using model analysis, we found the first four different frequencies (22.5, 28.9, 40.6, and 47.4 Hz) and vibration type, which suggested of a weak link. Further static structural analysis revealed that the deformation of the spindle was 67.26 μm. An experimental static rigidity analysis was performed, and the experimental deformation values of the tool and spindle were obtained. The static and dynamic characteristics, as well as the accuracy and efficiency of the finite element model, were verified by comparing the data with the Finite Element Analysis (FEA) results. Subsequently, we modified the settings and analysis model to ensure that the analysis results were consistent with the experimental findings. The error between the two results was within 1.56%. For an applied load of 5000 N on the spindle nose, the tool nose transient response was 0.5 s based on transient analysis. Under the condition that the structural deformation is as constant as possible, the lightweight structure may achieve the minimum weight and enhance the natural frequency; thus, the ideal structure will be obtained, and finite element analysis will then be performed. The optimal conditions for topology optimization include a lightweight structure, reduced structural deformation, and increased natural frequency of the structure. The developed method improves structural optimization, increases the ability of the product to be manufactured, and offers designers a variety of price-effective options.

“…Furthermore, it has been demonstrated that using the FEM for modelling milling machines is an appropriate technology for the modelling of milling machines as a whole. Te-Yen and Lee [11] used it for modelling a conventional milling machine, Zhang et al [12] for a High-Speed milling machine and Lopez de Lacalle and Lamikiz [13] refers it as a standard technique for this task. The same technique is also considered useful for modelling elements that are particularly critical for final machining precision, such as Amaral et al [14] demonstrates for the systems for fixing the piece and Rantatalo et al [15] for spindles.…”
