Abstract
Titanium is one of the most important materials, with almost 80% of Ti-6Al-4V being used in the aerospace industry. Drilling of titanium parts is one of the dominant processes in this industry. However, there are very limited studies on the effect of machining environments such as flood, MQL and cryogenic cooling in drilling titanium. This paper addresses this gap by investigating the effects of various machining environment in drilling titanium. Numerical modelling and experimental analysis showed that at high cutting speeds, cryogenic cooling can significantly reduce cutting temperature and therefore chemical affinity between cutting tool and workpiece materials. Cryogenic cooling resulted in minimised tool wear as compared to MQL and flood cooling. Furthermore, 43% reduction in average surface roughness was achieved using cryogenic cooling.
