Characteristics of Hole Machining for Brittle Material by Ultrasonic Longitudinal and Torsional Vibration
Takuya Asami, Hikaru Miura (Nihon Univ.) US2011-81
Abstract (in Japanese) (See Japanese page) 
(in English) The combination of ultrasonic vibration and polishing slurry has been shown to be an effective method for machining holes in brittle materials such as glass. However, conventional ultrasonic methods use only longitudinal vibration. 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. Removal rates and machining accuracy are expected to be improved by using ultrasonic longitudinal-torsional vibration. Therefore, we have developed a new method using polishing slurry together with ultrasonic longitudinal and torsional vibrators with diagonal slits for hole machining of brittle materials. In experiments, soda-lime glass is used as the processing material in ultrasonic complex vibration an ultrasonic longitudinal vibration, and hole roundness error and machining time are measured to assess the hole machining characteristics. As the result, the machining accuracy is improved by using ultrasonic longitudinal-torsional vibration.
