| Outline of Final Research Achievements |
In this study, we studied the machining principle of ultrasonic machining using complex vibration of longitudinal and torsional vibration for the purpose of upgrading and high accuracy of ultrasonic machining. The examination of the machining principle was carried out by obtaining machining characteristics such as machining mark and machining time when ultrasonic machining was performed on soda-lime glass. As results, we found that ultrasonic machining by complex vibration works by abrasive grain scraping off the machining target surface by torsional vibration. In addition, we found that the machining amount per grain of abrasive grain increased in the case of complex vibration compared with only longitudinal vibration. In other words, we considered effective to increase the machining speed by using larger torsional vibration and increasing the machining amount of the abrasive grains.
