Poster on EMVeM Industrial Workshop

Research concerns energy efficiency of machine tools in discrete manufacturing systems. Energy consumption of these machines is driven in principle by four factors: produced part description, chosen technological process, production machine characteristics and machine utilization, depending on the configuration of production line (transfer line, flexible manufacturing system etc.). Usually, produced part is defined by customer, therefore unchangeable, but the latter three factors can be optimally chosen to minimize energy consumption of a given production mission. Efforts are being undertaken to develop corresponding intermediate energy models of machine tool that have capability of instantaneously providing an approximate averaged energy per part without need of time simulation. Proposed modeling technique allow to predict energy usage of production line upfront, during the design phase. Additional work is focused on creating methodology for quick, industrially applicable energy characterization procedures of machines using conventional power meters and wireless sensor nodes acquisition system. There are several potentially high impact application for presented methodology. First concerns energy-aware design and configuration of new production systems, whereas the other can be seen as retro-fitting of existing production line by tuning process and machines parameters and effectively substituting parts of the production line with more energy efficient, modern equivalents.
