Abstract
Industrial development and application of new methods require extensive studies for getting main goals in manufacturing to minimize production, cost, energy, and resources along with improving the function. In this way, a cutting fluid plays an important role for extending tool life of the cutting tool. Because of this reason, the use of the cutting fluid has to have the proper coolant properties for decreasing cutting temperature and friction coefficient in machining processes. An experimental study is performed for investigating the cooling properties of Al2O3(aluminium oxide) nanofluid with Minimum Quantity Lubrication (MQL) method as the cutting fluid in the machining process. For evaluating the cooling properties of cutting fluid, friction coefficient has been measured by using Pin on Disk machining (ASTM G99). The Pin and Disk are made from carbide drill MWS1130LB and carbon steel SS400, respectively. The MQL technique with using nanofluids in the nanoparticle concentration of 1.2 vol. % and conventional cutting fluid or C5 coolant were tested at a volumetric rate of 250 ml/h and 15 liters/min, respectively. As a result, the observed nanofluid has the best performance for decreasing friction coefficient as 36% on 1000 rpm. However, the coolant properties of C5 coolant are better that Al2O3 nanofluid. It is due to the volume concentration of nanofluid is very high, so the performance of the fluid decreases.
