Optimization of turning parameters for minimum energy consumption / Mohd Khairuddin Che Long

Energy consumption during machining is one of the critical factor to determine a sustainable machining. By minimizing the energy consumption, a green manufacturing can be introduced. This research was about an experimental study to investigate the relationship of turning parameters like depth of cut, feed rate and cutting speed to the energy consumption for turning operation on AISI1018 Mild Steel by using a conventional lathe machine. The cutting tool used in the experiment was coated tungsten carbide inserts. Design of Experiment (DOE) is used to generate the number of experiments which consists of 20 set of experiments. The result is analysed using Response Surface Methodology (RSM) to determine the interaction between machining parameters to the energy consumption. The results revealed that the most significant parameter in minimizing the energy consumption is feed rate followed by cutting speed and depth of cut. Meanwhile, in two ways interactions between the parameters, it shown that the combination of spindle speed and depth of cut are the most significant to lower the energy consumption during the machining. RSM also generate interaction equation of each parameter with the percentage accuracy about 94%.
