In industry, the search for reducing energy consumption directly impacts the manufacturing sectors due to the high power consumption required for their processes. Thus, studies on machining centers that identify factors impacting this demand, while maintaining the quality of the surface finish on manufactured parts, are essential. The objective of this paper is to statistically analyze the influence of cutting parameters on energy consumption and surface finish on a Leadwell V40 iT machining center. A design of experiments (DOE) was developed using Minitab® software, with the depth of cut, spindle speed, and feed rate as input parameters. Each experiment was programmed using SprutCAM, measuring energy consumption and surface finish. The data obtained were statistically analyzed to determine the influence of the cutting parameters on the response variables, individually and in combination. The results show that the most critical factor for both responses is the depth of cut, with an F-value of 93.71 for surface finish and 36.20 for energy consumption, both presenting a P-value near zero. The composite analysis, aimed at optimizing the cutting parameters, shows an accuracy of 96.49% in minimizing these parameters.
