A Short Review on Minimum Quantity Lubrication Method in Machining Applications

Abstract

To maximize production while reducing environmental effect, the machining industry is always looking for new, sustainable, and cost feasible ways. One approach that shows promise in this area is Minimum Quantity Lubrication (MQL). The MQL approach is briefly reviewed in this work with an emphasis on its use in machining. At the beginning of the study, a basic introduction of the MQL method is given, and then its effect on tool wear, surface roughness, cutting temperature and the energy consumption is reviewed. In brief, this paper discusses MQL's lubrication methods, benefits, drawbacks, and applications in different machining operations. The outcomes demonstrated that the MQL efficacy is also affected by tool material, workpiece material, cutting conditions, and lubricant type. Therefore, it is worth to mention that this review emphasizes MQL's sustainability in machining lubrication. By balancing its pros and cons, this study hopes to help readers understand MQL and its potential to optimize machining operations in many industries.
