Abstract
This paper proposed a new cutting method employing ultra-low-frequency (ULF) vibration of less than several Hz generated by an NC program in order to achieve high performance dry machining of titanium alloys. The results of turning experiments at a cutting speed of 100 m/min showed that the developed method significantly reduces crater wear in machining of Ti-6Al-4V even under the 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.
