This paper presents an investigation into the minimum quantity lubrication mode with Nano fluid during turning of titanium (TI6AL4V) alloy. In heavy cutting conditions, minimum quantity lubrication (MQL) has been observed, that, Nano-cutting fluids which have enrich thermal conductivity than base fluid, are begun to be used in MQL system. The addition of the required nano particle ratio to the base liquid is one of the most important issues that arise in this method. Therefore, this study aimed to find the optimum distribution rate of graphene nano particles having excellent properties and machining parameters. To do this, graphene nano particles were added to a vegetable-based cutting solution. Nano-cutting fluids were prepared in different volumetric concentrations. When turning of titanium (TI6AL4V) alloy, these Nano fluids were used in the MQL system. Three different parameters were added to the experimental design to study the performance of Nano fluids under several cutting conditions. i.e., speed, feed rate and depth off cut. Apart from this experimental design, three tests were carried out at each concentration ratio while keeping the machining parameters constant to clearly see the impact of concentration rates on surface roughness, flank wear. And crater wear. In addition, while chipping/fracture, were observed under all cutting conditions

Machining is the most fundamental process in manufacturing industry. The heat generated on the working surface of the tool during machining is critical to determining the dimensional accuracy and surface quality of the workpiece. Conventional cutting fluids are hazardous to the health of workers and cause environmental pollution. This paper focuses on the effect of vegetable oil-based nanofluid on the machining performance in turning of EN19 steel through Minimum Quantity Lubrication (MQL). Canola oil is used as a base lubricant with various inclusions of boric acid powder nanoparticles. Machining parameters such as tool temperature and cutting forces are measured during machining. After processing, the surface roughness of the part is measured. The change in the temperature of the cutting tool and the roughness of the processed surface, depending on the cutting speed and feed, is studied at various percentages of suspensions of nano boric acid in canola oil. From the results of analysis it is found that cutting force, tool temperature and surface roughness decreased with increasing percentage of boric acid nanoparticles. [ABSTRACT FROM AUTHOR]
