Abstract Environmental concerns call for the reduced use of cutting fluids in metal cutting practice. Minimum quantity lubrication (MQL) machining is one of the promising solutions to the requirement for decrease in cutting fluid consumption. This paper reports the results of an experimental work to investigate the effect of a well-designed MQL set up on machining constraints like tool forces and surface finish. It was found that machining with the MQL set up produced better results in terms of lesser cutting forces and better surface finish in comparison to dry and wet machining.

Keywords: MQL machining, Nozzle design, cutting force, Surface finish
