Effect of Minimum Quantity Lubrication when Turning a Steel Grade

Abstract:

In turning operations a coolant is usually introduced to the cutting zone to reduce the friction developed at the tool-workpiece contact area and remove heat generated because of this rubbing action. Conventionally, a coolant is introduced into the cutting zone in excessive quantities. However, a lot of concern has been raised recently as a result of the uncontrolled using of coolants in the metal cutting industry. Therefore, the concept of minimum quantity lubricant (MQL) has been introduced recently. In this paper, the principle of MQL is utilised in machining of a steel grade. The performance of MQL in terms of surface finish is evaluated against both, the flood coolant and dry cutting modes. The results obtained show that MQL produces acceptable surface finish. Therefore, it is highly recommended to consider the application of MQL instead of flood cooling when turning steel grades.
