The ever-changing legislation and every increasing awareness of the environment have led to a change in the production processes used up to new and especially in the production auxiliaries such as coolants. It has been widely accepted that a considerable proportion of the process costs are caused by the application of metalworking fluids. In this aspect the costs for coolant concentrates themselves played an insignificant role. The actual cost are caused by system costs, labour costs for the care and monitoring of materials, coolant recycling and water purification system and last, but not least, the cost for disposal. Despite the trends towards "dry cutting" and low friction tool coatings, there is still a need for cutting fluids, or coolants, because of their ability to improve product quality, remove heat and swarf from the tool/workpiece interface and increase tool life. This has led to much more attention being paid to the Minimum Quantity Lubrication (MQL) system. In this particular research, turning of Cast Iron (CI) work pieces with MQL system has been carried out. The influences of MQL on tool wear mode/mechanism and surface roughness of workpiece was assesed and compared with conventional flood-type coolant system. In short, the results showed that surface finish and tool wear were all affected beneficially with all the MQL techniques compared to original flood-type coolant system.
