Resumen
Awareness of socioenvironmental damages caused by the use of mineral oil- based cutting fluids has increased the search for more sustainable options, as the case of cryogenic fluids such as liquid nitrogen (LN2). The objective of this work is to measure and analyze the wear of the cutting tool under different cooling media, in order to compare them with the use of LN2. Flank wear and cutting tool life were monitored. On comparing dry, wet and LN2 conditions, it was found that, in average, the LN2 condition provided better results compared to the dry and wet conditions, but not so much distant from these conditions.
