Abstract

The impact of various additives such as Al2O3, polycrystalline diamond (PCD) and graphite as well as water in MQL oil has been investigated on convective heat transfer and machinability in end milling Ti6Al4V for the first time. The analysis indicated that suspending PCD in oil improves heat transfer by 43% from 557 W/m°K in conventional MQL to 970 W/m°K resulting in 1.6 times increased tool life in high speed machining of Ti6Al4V alloy. This can potentially allow for high speed end milling of Ti6Al4V titanium alloy resulting in increased productivity.
