Abstract

Increased cost associated with the use of coolant in machining operations, increased environmental awareness, and strict protection laws and health regulations for occupational safety demanded elimination/reduction of cutting fluids in metal cutting operations. Minimum quantity lubrication (MQL)/near dry machining (NDM), which relies on total use without residue has been gaining popularity as a new alternative for flood cooling. The quantity of cutting fluid in MQL is in ml/hr instead of in l/min as in flood cooling. The paper begins with an overview regarding the problems associated with the use of conventional flood cooling method leading to the need of MQL, and subsequently discusses the components and working principle of MQL system. The literature related to turning and milling operations has been reviewed and presented in two major headings: effect of operating parameters on MQL performance and effect of MQL on machinability to provide a clear and complete understanding of the system.
