Item Eco-efficient and highly productive machine tools by means of an holistic eco-design approach(2010) Zulaika, Juan Jose; Dietmair, Anton; Verbeeten, Wilco; Campa, Francisco Javier; De Lacalle, Luis Norberto López; MAQUINASMachinery manufacturers are facing the challenge of designing machine tools that are productive, accurate and reliable and that at the same time consume the least possible amount of material and energy resources. In view of this, this paper presents a multidisciplinary methodology for designing milling machines that achieve a high level of productivity while at the same time ensuring high machining quality and less energy consumption during their use phase. Following this methodology, an eco-productive milling machine has been designed and manufactured which, combining different technologies (light materials, active vibration damping system etc.), has managed to reduce the inertias involved in servo-drives by over 50%, with a corresponding reduction in energy consumption, whereas the productivity of the machine - measured in terms of metal removal rate- has been increased by 100% in such a way that productivity and eco-efficiency have been combined in a single machine: the eco-productive milling machine.Item New concepts for structural components(Springer London, 2009) Zulaika, Juanjo; Campa, Francisco Javier; MAQUINASThis chapter is focused on analysing new concepts and trends related to the structure of machine tools. In fact, the structure of the machine has a decisive influence on the three main parameters that define the capabilities of a machine, which are: motion accuracy, the productivity of the machine and the quality of machining. In this respect, this study on structural components will add a new basic parameter, eco-efficiency, because the structure of the machine also has a decisive influence on the whole life cycle of the machine and especially on the materials and energy resources consumed: an issue of increasing concern among machine tool builders.
