| Outline of Final Research Achievements |
In order to achieve high performance machining of Ti alloys, this study proposed a new cutting method employing ultra-low-frequency (ULF) vibration of less than several Hz generated by using a numerically controlled machine tool axis and an NC program. The results of turning experiments showed that the developed method significantly reduces crater wear in machining of Ti-6Al-4V even under the dry machining conditions. Moreover, the mechanism that ULF vibration affects and the influence caused by actual cutting time and non-cutting time in each individual vibration period on the amount of crater wear were investigated. As a result, it was found that the developed process is a promising method for achieving a high performance dry machining of titanium alloys.
