Energy assessment of different cooling technologies in Ti-6Al-4V milling

Abstract Manufacturing craves for more sustainable solutions machining heat-resistant alloys. In this paper, an assessment of different cooling lubrication approaches Ti6Al4V milling was carried out. Cryogenic cutting (liquid nitrogen) and conventional (oil-based fluid) were assessed with respect to dry cutting. To study the effects main relevant process parameters, proper energy models developed, validated then used comparing analysed strategies. The model parameters identified exploiting data from specifically conceived experiments. power out considering perspectives, a bottom-up approach. Indeed, it found that cryogenic cooling, thanks better tribological behaviour, is less demanding (at least 25%) than If spindle considered, lower saving percentages can be expected. showed its best performance (from 3 11 times) if machine tool perspective analysed. Considering even primary required producing fluids, requires up 19 times
