Use of MQL for Taper Turning Operation

In present study, it has been surveyed that, the metal industries using the cutting fluid has become more problematic in terms of both employee health and environmental pollution. Minimum quantity lubrication (MQL) has increasingly found its way into the area of metal cutting machining and in many areas, has already been established as an alternative to conventional wet processing. In contrast to flood lubrication, minimum quantity lubrication uses only a few drops of lubrication (approx. 5 ml to 100 ml per hour) in machining. The aim of this research is to determine if the minimal quantity lubrication (MQL) technique in turning gives some advantages in terms of workpiece surface roughness using workpiece material as EN-31 steel and carbide cutting tool material. Fluid selection is important for MQL because it must be a superior fluid such as vegetable oil or synthetic oil. The costs of these superior fluids are higher but eliminate the need for costly fluid recycling and disposal services. It was found that, MQL produced better surface finish as compared to wet machining. The result can significantly reduce cost and environmental pollution.
