Paper Abstract

Subsurface damage (SSD) caused during machining process can decrease the mechanical strength of BK7 glass optical elements, which would shorten the lifetime. Rotary ultrasonic face milling (RUFM) is interest of many engineering applications, especially for machining optical glass which need the high surface quality and less SSD depth. In this paper, the effects of several critical factors (i.e. spindle speed, feed rate, and cutting depth) on machining quality and efficiency in RUFM were investigated experimentally and further analyzed. The relationships between the process parameters and the machining quality were obtained. Moreover, an optimized method was proposed for the further applications of RUFM, taking care of both machining quality and efficiency.
