The State of the Art in Energy Consumption Model – The Key to Sustainable Machining
Development of reliable energy consumption models is the essential step toward sustainable machining. Due to the complex relationship between energy consumption and a large number of contributing factors, obtaining an accurate model is very difficult, if not impossible. This paper aims to review the literature in this field over the last two decades. The research work on energy models is grouped into three categories, i.e. theoretical, experimental and discrete event-based models. It is found that machine tool structure, set-up conditions, and machining parameters have major impacts on energy consumption, suggesting that energy consumption models need to be constructed not only at the process level but also at the system level. Hybrid models that combine more than one approach are considered an option.
