Abstract

Ultra-precision raster machining (UPRM) is an enabling ultra-precision machining technique for the wide fabrication of high-precision freeform surfaces, which offers nanometric surface roughness and sub-micrometric form error. In UPRM, many factors downgrade such high-quality machining surfaces, such as spindle vibration, material properties, tool wear, tool vibration, cutting conditions. However, spindle vibration yields a crucial impact upon surface formation. In this chapter, the cutting mechanism of surface formation in UPRM has been presented with details, covering two cutting strategies (Horizontal cutting and vertical cutting), two cutting directions (Up-cutting and down-cutting), etc. According to the linear momentum principle of Newton and the angular momentum principle of Euler, a five-degree-of-freedom dynamic model of an aerostatic bearing spindle has been proposed for spindle vibration with linearized Newtown-Euler equations under the excitation of intermittent cutting forces in UPRM.
