Characteristics of Hole Machining of Brittle Materials by Ultrasonic Longitudinal-Torsional Vibration -- Relationship Between Processing Pressure and Machining Time --
Takuya Asami, Hikaru Miura (Nihon Univ.) US2012-84
Abstract (in Japanese) (See Japanese page) 
(in English) The longitudinal-torsioanl (complex) vibration is obtained by mean of diagonal slits. Also, complex vibration sources with diagonal slits have been applied to ultrasonic motors and ultrasonic welding; in contrast, few studies have been conducted on ultrasonic machining using complex vibration and polishing slurry. Therefore, we have developed a new method using polishing slurry together with ultrasonic longitudinal and torsional vibration source with diagonal slits for hole machining of brittle materials. In this study, using soda-lime glass as the processed material, the machining characteristics of a hole (diameter: 8 mm; depth: 4 mm) created using complex or longitudinal vibration sources are measured by varying the pressure during processing. As results, the machining time when using a complex vibration source is notably shorter as compared with that using a longitudinal vibration source at the optimal processing pressure. Secondly, in contrast with longitudinal vibration source, the machining speed of complex vibration does not decrease with increasing the processing depth in this measurement range.
