Design and experimental research of microquantity lubrication device used in the in situ cutting of aircraft titanium alloy structural damage

Abstract

Contrapose the question existing in that compound droplets generator used in the laboratory is not suitable for field, this paper design and manufacture a new device based on gas driving, and using the device for a titanium alloy drilling test. Experiment shows that wet minimal quantity lubrication (Wet MQL) can be used in in situ cutting due to its good lubricating effect, and without damage to electrical equipment of aircraft. The designed generator of compound droplets is suitable for field use for a simple structure, wide range of parameter adjustment, and easy to carry. © 2014 Springer-Verlag.
