Abstract (EN): This caper introduces a framework for the Ecodesign of sheet metal cutters, which targets the definition of a set of design guidelines for this type of machine-tools, based on the contribution of the main equipment sub-systems to the processing and environmental impacts associated to their electrical energy consumption. A comparative study of commercially available Laser cutting equipments, using CO2 or doped fiber as the energy source, is described. Two parallel analysis of electricity consumption have been carried out: (1) the observation of CO2-Laser cutters usage, production mods and work conditions in real industrial environments, and (2) a comparison between these and a Fiber-Laser equipment, for a similar work order (material and thickness). The specific process, energy with the different equipments was calculated, and confirms the importance of alternative technologies and practices for the energy efficiency of machining processes.
