Influence of Various Parameters of Turning Low Carbon Steel with M2 HSS Tool Using Minimum Quantity Lubrication 2022-28-0533

Turning is a widely used manufacturing process in mechanical machining industries, while the cost associated with this process is high due to the cost involved in changing tools or tool regrinding. All the parameters of turning, like feed rate, cutting speed, and depth of cut, substantially impact the tool wear, which subsequently reduces tool life. Cooling methods like flooding, Minimum Quantity Lubrication (MQL), etc., are incorporated to minimise these effects on the tool and workpiece interface. When using these cooling techniques, the process parameters involved play vital roles in increasing the effectiveness. This paper focuses on the effects of machining parameters on the tool and the workpiece quality. Experiments were conducted to study the impact of various input parameters of the turning process on the tool tip temperature, cutting forces, and tool wear, ultimately affecting the tool's life. The average cutting forces are reduced by 60 N, a 30 % reduction in the forces is seen. The average surface roughness has a 2.02 μm reduction, which is a 30 % reduction when compared. These results emphasise the need for a tradeoff between the cooling and lubrication rates when using cooling techniques.
