Modeling of dynamic characteristic of the aerostatic bearing spindle in an ultra-precision fly cutting machine

A review of machine-tool vibration and its influence upon surface generation in ultra-precision machining

“…However, since the spin has only been idealized as a short shaft, the conventional physical models are generally simplified to only analyze the radial motions but not the tilting motions. An et al [37] built a dynamic model of angular displacement of a spindle for tilting motion based on Euler equations. Further, Zhang et al [14,[38][39][40] developed a five-degree-of-freedom model of a spindle to describe axial motion, radial motion and tilting motion.…”

“…Zhang et al [33,34] found that in UPM the frequency range covered from dozens of Hz to dozens of kHz. Based on the physical origins of vibration, the vibration in UPM can be categorized into tool tip vibration [13,16,[33][34][35], spindle vibration [14,[36][37][38][39][40], material induced vibration [32], tool hold vibration, slide vibration and table vibration; all would affect surface roughness and form error. However, the vibration in UPM has not been understood fully.…”

Dynamic characteristics of an aerostatic bearing spindle and its influence on surface topography in ultra-precision diamond turning

“…Marsh [31] discussed the effects of spindle dynamics on topographies of flat surfaces in precision fly-cutting. An et al [32] experimentally and theoretically identified how the tilting motions of the aerostatic bearing spindle influences topographies of machined surfaces in ultra-precision fly cutting. However, in UPDT, little work has been conducted on the aerostatic bearing spindle vibration under external excitation of cutting forces in the cutting process and fewer have discussed its effects on surface topography.…”

Research progress on ultra-precision machining technologies for soft-brittle crystal materials

“…In China, An et al [20], Liang et al [21,22], and Chen et al [23] at Harbin Institute of Technology developed an SPDT equipment (as shown in Fig. 4 [23]) and presented the design philosophy of an ultra-precision fly cutting machine tool based on machining material properties and processing requirements.…”
