Abstract
Traditional flood lubrication on machining processes involves a severe environmental risk due to the high quantity of contaminant that is deposited on the atmosphere. For this reason, the search of more sustainable lubrication methods is necessary. This paper analyses the minimum quantity of lubricant (MQL) procedure on the turning of copper-nickel ASTM B122 alloy in terms of cutting forces and surface integrity in comparison to dry cutting, using two different cutting oils: a synthetic vegetable oil and a synthetic mineral one. The aim is to find out the lower limit of cutting oil flow rate needed to improve the cutting condition. The results show that MQL conditions improve the efficiency of the turning process of this alloy, being effective in cutting force reduction and limiting the surface adhesions and defects. Besides, vegetable oil performance is better than mineral one. It has been found that flow rate needed depends on the depth of cut.
