Titanium and its alloys are well known as difficult-to-machine materials due to low thermal conductivity and chemical adherent to cutting tools. Ti6Al4V is most widely used in a thin-wall structure application in the field of aerospace industry. Thin-wall machining encounters vibration and that furthermore increases fluctuations in cutting force. Select the type of machining process that generates sustainability in thin-wall machining is crucial to master. One of the innovations in conventional machining is to promote vegetable oils as the cutting fluids. These cutting fluids offer environmentally friendly cooling as well as lubrication to foster the cleaner production in the aerospace industry. Hence, the capable, sustainable cutting fluid has to be a future of the machining process. Minimum quantity lubrication (MQL) using coconut oil is recognised to be the green machining technique in milling titanium alloy. Coconut oils as nanofluids are attracting considerable attention due to good lubrication properties, non-toxic and biodegradable nature, and easy recycling. Therefore, it is a significant finding to observe the stability, dynamic behaviour, surface quality, and environmental aspects of cutting fluids in milling thin-walled Ti6Al4V. The findings reported in this chapter show that the use of coconut oil in the MQL system for thin-wall machining of Ti6Al4V is a promising innovation in the future of aerospace industries. At last, this chapter also sheds light on the treatment of exhausted cutting fluids.
