Abstract
The MQL (minimum amount of lubricant) is always an alternative to flooding when looking for reduction of oil consumption. There are authors who defend the improvement of machining force, increase tool life and decrease energy consumption due to the withdrawal of the high pressure pump from the flood system, although there are divergences. A literature review has shown that many predictive models of machine tool power consumption do not consider the consumption of the required air compressor in MQL. These models are based on a study carried out in 2006 at MIT. Withal, they are still under development with some calculations oversized, while others ignore components of the machining center. This paper’s motivation was the divergent points analysis and test models to predict the energy consumption of machine tools using MQL and flooding. These tests were performed in a comparative manner between the two techniques in a machining center adapted for MQL. Tool life and cutting forces were also measured. The machining process chosen was the through-hole in gray cast iron. It was found that the amount of energy consumed in the cutting is lower when compared to the consumption of basic components of the machine tool. Using the MQL, the tool life showed a decrease. However, it allows the feed to increase and reduces the energy consumption.
