Abstract
In the recent years a lot has been done to avoid the cutting fluids from the production. Dry cutting and semi-dry cutting such as minimum quantity lubrication (MQL) have been favored by the industry. However, one of the main limitations in the application of MQL is that the full mechanism has not yet been fully understood. This paper presents the effects of minimum quantity lubrication (MQL) on the turning performance of aluminum alloy 6082 as compared to completely dry and wet machining in terms of tool wear, surface roughness and cutting forces. It was also seen from the results that the substantial reduction in tool wears resulted in enhanced tool life and surface finish. Furthermore, MQL provides environment friendliness (maintaining neat, clean and dry working area, avoiding inconvenience and health hazards due to heat, smoke, fumes, gases, etc., and preventing pollution of the surroundings), and improves the machinability characteristics.

Key words
