Optimization of Turning Parameters of Al 6063 with Analysis of Surface Roughness and Vibration Under Minimum Quantity Lubrication Condition

Aluminum alloys are widely applied in almost all the industries due to its distinctive characteristics like less weight, good thermal conductivity, corrosion resistance etc. Machining is inevitable in manufacturing processes as it can be used to accomplish any shape with high precision. The negative aspects of conventional wet machining drive researchers to search for different alternatives. Minimum Quantity Lubrication (MQL) is one such prominent and successful substitute. Turning is one of the foremost machining processes performed on cylindrical jobs. In this study, the cutting parameters engaged during turning under MQL carried out on Aluminum 6063 alloy are optimized to improve surface quality and also with the development of regression equations, the surface roughness is predicted. Vibration during turning is studied and correlated with surface roughness to find the influence. The contribution of cutting speed, depth of cut, feed rate, cutting tool nose radius and overhanging length of workpiece on surface roughness is also determined in turning. The optimum combination of cutting parameter levels for minimum surface roughness in turning is found and recommended for economic and efficient machining of Aluminum 6063 alloy under MQL condition.
