Subcomponent Developments for a Vortex Machining Test Facility

摘要

The goal of this research is to deterministically control sub-millimeter sized vortices produced by oscillating probes submerged in abrasive slurries to remove material in highly localized regions. Probes of varied diameters (7 urn to 0.5 mm), oscillating at high frequencies (over 100 Hz and up to 40 kHz) will produce localized vortices of varying size and magnitude. Slurry vortices generated at a specimen surface have been shown to produce material removal (MR) footprints with sub millimeter lateral dimensions [1]. The size of the process footprint will be controlled by the amplitude and frequency of the driving oscillations, and the orientation of the probe with respect to the workpiece.
