N2 - Owing to the less heat generation, low noise contamination, high precision, and low friction of air bearings, it has been generally adopted for the aerostatic bearing spindle widely employed in ultraprecision machining (UPM). However, its dynamics have a crucial impact upon high-quality surfaces with nanometric surface roughness and submicrometric form error in UPM. In the chapter, the dynamic characteristics have been presented with natural frequencies and dynamic responses for the linearized Newtown-Euler equations under the excitation of the intermittent cutting forces of ultraprecision raster milling (UPRM), following the previously proposed five-degree-of-freedom spring-mass-damper dynamic model of an aerostatic bearing spindle for spindle vibration. Further, the effects have been discussed on the dynamic responses of the spindle under its eccentricity, cutting conditions, etc. in UPRM, following the previously proposed five-degree-of-freedom spring-mass-damper dynamic model.
