A Study of Glass Milling Using Rotary Ultrasonic Machining

Abstract:

Article Preview

Employment of rotary ultrasonic machining (RUM) technique to mill glass material was attempted in this research. The feasibility and efficacy of the novel milling process were evaluated. The challenge of the attempt in the present study had to do with the fact that the direction of RUM tool oscillation was inherently perpendicular to the direction of milling. The RUM apparatus employed for the study comprised a computerized feeding system, a drive control system and an ultrasonic oscillation system. The RUM system was also characterized by having a feeding system fit for a PC-controlled stepping motor. It was found that the oscillation associated with the RUM milling was effective in reducing the machining resistance encountered during milling process, making it possible to increase the feed rate and thus the material rate, as well. However, the increased milling depth and feed rate would have an adverse effect on the tool life in terms of more breakage of grinding grits on the tool, thus resulting in faster wear rate of the milling tool.
