Effect of Al2O3 Nanolubricant with SDBS on Tool Wear During Turning Process of AISI 1050 with Minimal Quantity Lubricant

A nanolubricant is a new kind of engineering lubricant made of suspended particles in a base lubricant. It offers quality-machined part with minimum power consumption during machining. However, the application of nanolubricant without surfactant leads to agglomeration after a certain period of time. Hence, this paper investigates the effect of Al2O3 nanolubricant with surfactant Sodium Dodecylbenzene Sulfonate (SDBS) on tool wear during turning process of AISI 10150, mild steel bar with minimum quantity lubricant. Different cutting fluid conditions namely; dry; nanolubricant and nanolubricant with SDBS surfactant were tested. Tool wear rate were evaluated at constant cutting speed of 1273 rpm, feed rate of 0.2 mm/rev, and depth of cut of 0.1 mm. The results exhibit positive influence of Al203 nanolubricant with surfactant in alleviating tool wear during turning operations.
