ARDILA, María I. et al. Study of energy consumption in Haas UMC-750 and Leadwell V-40iT® CNC machining centers. Ing. compet. [online]. 2022, vol.24, n.2, e21211377.  Epub May 26, 2022. ISSN 0123-3033.  https://doi.org/10.25100/iyc.v24i2.11377.

Machining centers are complex equipment that demand high energy consumption affecting the production costs. Different studies have related some factors with the energy consumption; however, it is not completely clear which variables or factors have a greater incidence in this energy consumption of these machining centers without decreasing the quality of the finishing surfaces of the manufactured parts. In the present study, an analysis of the influence of cutting depth, forward velocity and spindle speed on the energy consumption and roughness of the surface finish was carried out in the Haas UMC-750 and the Leadwell V-40iT® machining centers. An experiment was developed with an nK factorial design keeping some variables as constants such as the base material, the cutting tool and the machining path. The results obtained showed that by increasing the feed rate, energy consumption can decrease by up to 50% for the machining centers studied without influencing the surface quality. Besides, the interaction between the factors was evidenced, identifying that the cutting depth has a moderate influence on the roughness or surface finish of the manufactured parts. The energy consumption varies for each machining center and the experimental design developed helped to characterize the influence of some cutting variables on the energy consumption of each machining center.
