“…Yin et al (2004) developed a kind of high-quality grinding protocols for polycrystalline silicon carbide spherical surfaces and achieved surfaces with form accuracy peak-to-valley (PV) of 0.21-0.59 wave length (0.13-0.37 m) and surface roughness of 9.92-17.22 nm Ra. Liu et al (2006) analyzed the mechanism of surface machining of nano-ceramics materials in ultra-precision grinding processes and gave a new formulation for critical grinding depth. As a high efficiency and precision method, machining with ultrasonic assistance have brought a new alternative technique to traditional way for nano-ceramic machining.…”

“…On the other hand, in ultra-precision micromachining of brittle materials, elliptical vibration was capable of ductile machining without a brittle mode [11]. And Zhao et al discussed theoretical critical grinding depth based on the ductile removal mechanisms of ultrasonic vibration grinding for the ceram-ics [5,12,13]. This paper studied the ultrasonic vibration effect of diamond grinding tool on the ceramic machining.…”

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.
