ZULUAGA, Efraín et al. Energy consumption during surface texturing of AISI 1080 and AISI 52100 steels using CNC machining. Ing. compet. [online]. 2022, vol.24, n.2, e20711301.  Epub 26-Maio-2022. ISSN 0123-3033.  https://doi.org/10.25100/iyc.v24i2.11301.

Surface texturing has been used in diverse applications to improve the tribological performance of mechanical components in contact. In particular, the imposition of a deterministic texture on metal surfaces through machining processes has energy costs associated with the consumption of electrical power, the wear of cutting tools and the inherent losses due to the transformation of electrical energy into mechanical energy, among others. Quantifying the energy consumption in texturing processes helps to evaluate the viability of increasing the areas to be textured, i.e., the total volume of material to be removed from the pieces. In this work, the surface texturing process of AISI 1080 and AISI 52100 steels with five geometric patterns was studied, with emphasis on the analysis of energy consumption in the machining center. Electrical energy consumptions between 31.8 and 52.3 Wh per mm2 of textured area were recorded and correlations between energy consumption, material, geometric design of the texture and textured area were established from the experimental data. An increase of 14% in energy consumption was found by rising the textured area for AISI 1080 steel, as opposed to AISI 52100 steel, which showed a reduction of energy consumption of 20.8 % when the textured area increased.
