Energy-efficiency based classification of the manufacturing workstation

摘要: EU Directive 92/75/EC established for the first time an energy consumption labelling scheme, further implemented by several other directives. As consequence, nowadays many products (e.g. home appliances, tyres, light bulbs, houses) have Energy Label when offered sale or rent. Several models of manufacturing equipments been also developed. This paper proposes efficiency – based classification workstation, aiming to characterize its energetic behaviour. The concept workstation is defined. On this base, a methodology has It refers specific criteria and their evaluation modalities, together definition & delimitation classes. class position defined after amount needed in middle point operating domain, while extension determined value coefficient from Taylor series that approximates dependence between consume chosen parameter working regime. main domain interest looks be optimization activities planning programming. A case-study regarding actual lathe view, on two different approaches (analytical numerical) included.
