“…Several experimental investigations revealed that RUM is a cost-effective machining method for difficult-to-machine materials [9,10]. RUM also provides 6-10 times higher material removal rate (MRR) than conventional grinding with a relatively low cutting force, which helps to achieve high tool life, high machining accuracy, low machining temperature, and low surface roughness [7,11,12].…”

Abstract:Rotary ultrasonic machining (RUM) is a nontraditional and cost-effective machining method for hard and brittle materials, such as ceramics, optical glass, composite materials, and so on. RUM is a hybrid process that combines the material removal mechanisms of diamond abrasive grinding and ultrasonic machining. In RUM, a rotating cutting tool with metal-bonded diamond abrasive particles is ultrasonically vibrated in the axial direction while the tool spindle is fed toward the workpiece at a constant feedrate to remove material. It has been reported that continuous rotary ultrasonic machining has been successfully used to drill holes in K9 glass. Intermittent rotary ultrasonic machining is a newly introduced ultrasonic machining process, which uses a slotted cutting tool instead of a common metal bonded diamond cutting tool as used in continuous rotary ultrasonic machining. There has been no reported study to compare the effects of intermittent RUM and continuous RUM when machining K9 glass. This paper, for the first time, presents an experimental investigation to compare intermittent RUM and continuous RUM when machining K9 glass from the perspectives of cutting force, surface roughness, and chipping size.

“…Coolant is pumped through the hole in the middle of the drill to flush away the debris, prevent jamming of the drill, and keep it cool. RUM has been employed to drill 4 holes in stainless steel (Cong et al, 2010), titanium alloy (Qin et al, 2009), ceramics (Zeng et al, 2005), and ceramic composites , but never on this type of CFRP.…”

“…For this reason, ultrasonic assisted machining, which is a hybrid process that combines the material removal mechanism and ultrasonic vibration, has been considered. This process can be useful for ceramic machining because an additional axial ultrasonic vibration can lead to reduction in cutting temperature and tool wear while maintaining high surface quality, which cannot be obtained from conventional machining [6][7][8][9][10]. Therefore, ultrasonic assisted machining has been applied for machining of the ceramics as an alternative method to traditional machining [9].…”

“…Therefore, ultrasonic assisted machining has been applied for machining of the ceramics as an alternative method to traditional machining [9]. Several studies have been performed for machining of hard and brittle materials using ultrasonic vibration, which applied to either work material or a cutting spindle [2,6,7]. From the literature, it was found that better surface roughness and fracture strength were obtained.…”

In this work, machining test was carried out in various machining conditions using ultrasonic vibration capable CNC machine. For work material, alumina ceramic (Al 2 O 3 ) was used while for tool material diamond electroplated grinding wheel was used. To evaluate ultrasonic vibration effect, grinding test was performed with and without ultrasonic vibration in same machining condition. In ultrasonic mode, ultrasonic vibration of 20 kHz was generated by HSK 63 ultrasonic actuator. On the other hand, grinding forces were measured by KISTLER dynamometer. And an optimal sampling rate for grinding force measurement was obtained by a signal processing and frequency analysis. The surface roughness of the ceramic was also measured by using stylus type surface roughness instrument and atomic force microscope (AFM). Besides, the scanning electron microscope (SEM) was used for observation of surface integrality.
