The use of hard brittle materials has become increasingly more extensive. However, it is time-consuming to mill hard brittle materials with traditional metal-cutting techniques that use abrasive wheels. In addition, the tool would suffer excessive wear as well. As the efficacy of using hard brittle materials has increased in recent years, processing such materials for part fabrication has become a challenging problem difficult to solve. However, if ultrasonic energy is applied to the milling process and coupled with the use of hard diamond grits, hard brittle material can be effectively removed. Rotary ultrasonic machining (RUM) is mostly used in brittle material drilling. Few researchers have focused on the milling application by RUM till now since the milling process is categorized as a horizontal machining mode, whose motion is perpendicular to the longitudinal kinetic energy supplied by the RUM. Besides, the most important hammering action associated with RUM cannot manifest itself, leaving only abrasion action generated by the tool rotation and micro-vibration effective. Therefore, based on this kind of machining process, the easiest and the most effective way to increase the efficiency of the ultrasonic milling is to find out the optimal feed rate and depth of machining. The present research was aimed to apply the principles and characteristics of RUM for removing hard brittle material and investigating the interactive effect of the feed rate and the depth of machining on surface roughness of the milled hard brittle material. Finally, we attempt to find out the overall efficacy of utilizing the RUM for milling hard brittle material.
