Evaluation of the Environmental Impact of different Lubrorefrigeration Conditions in Milling of γ-TiAl Alloy

Conventional manufacturing techniques have not been subject to much scrutiny by industrial ecologist to date. The implementation of environment-friendly methodologies in metal cutting is, consequently, of considerable direct economic, social and technological importance. This paper aims to analyze the milling operation of a non conventional material such as γ-TiAl alloy from an environmental point of view, taking into account the impact of such material removal process in its various aspects. In particular, three kind of cooling conditions, namely wet, Minimal Quantity of Lubrication (MQL) and dry have been analyzed. Furthermore, for each coolant condition, different process parameters (i.e. cutting speed and feed rate) have been considered during milling operation in order to evaluate their environmental impact.
