Abstract
Purpose
The purpose of this paper is twofold. First review the relevant literature in machining using minimum quantity lubrication (MQL), contrast the economical, environmental, and technical attributes of this technology to conventional flood‐cooling techniques. Second highlight areas of relevant future research.
Design/methodology/approach
The approach consists of describing the essential elements of MQL as a technology, reviewing the relevant research by focusing on the most frequently used machining processes in this industry, highlighting the findings as they compare to flood cooling, and pointing to directions of required research in this technology.
Findings
The application of MQL in machining has shown better results in some processes; including in drilling, a cleaner environment, and a more cost‐effective machining technology. Further research is required however to better understand the underlying cause an effect phenomena in machining using microlubrication technology including environmental and health effects of this technology.
Practical implications
The paper provides a body of knowledge required for all stakeholders to better use or design machining systems using microlubrications.
Originality/value
This paper focuses on the state of the art of MQL and how it contrasts with conventional methods of machining.
