Energy Efficiency Optimization of Joining Processes on Shop Floor and Process Chain Level

Research has shown that the energy demand for manufacturing processes is frequently dominated by secondary consumers, especially since these are often neither controlled nor accounted for by corresponding primary processes. Secondary consumers are often continuously operating on high load, independent of the supported core processes’ operational state – e.g. downtimes. This perception has lead to a methodical approach, calculating an energetic performance indicator that can be actively influenced by both, manufacturing and technology planning as well as production planning. The case presented focuses a joining application wherein the detailed analysis on the shop floor lead to approaches on process chain level.
