Influence of Cutting Parameters on the Energy Consumption of a Leadwell V40 it Machining Center

One of the main objectives worldwide is to improve energy efficiency, and the manufacturing sector is no exception due the high levels of energy consumption necessary to carry out its transformation processes. As a result, the way machinery operates should be reconsidered. The purpose of this article is to present the results of a study on the influence of several cutting parameters on the energy consumption of a Computer Numerical Control (CNC) machine, a Leadwell V40 iT, during 3-axis machining. The parameters under analysis are feed rate, depth of cut, and stepover of the tool. Besides, the machining strategy was programmed in SprutCAM. An experiment was designed to determine the interaction of different cutting parameters and the energy consumed by the machine, which was measured with a Fluke 1735 Power Logger. The obtained data were statistically analyzed employing a factorial model to determine the optimal values of the three variables understudy, and thus establish the conditions that would produce the minimum energy consumption of the machine. The results show that the most critical factor in energy consumption is feed rate
