Abstract:

To estimate the energy consumption in the manufacturing process of a new product, a knowledge-based prediction method is proposed in this paper. In this method, first, the ontology technology is used to explicate the calculation and management of energy consumption, and a semantic model of energy consumption knowledge and its semantic representation are proposed. Then, a case retrieval process and a method of ease result reuse are presen- ted in view of the characteristics of energy consumption. Moreover, an energy consumption prediction model corre- sponding to manufacturing parameters is established by means of neural network. The effectiveness of the model is finally verified by the machining process of a blade. Thus, a hierarchical framework of energy consumption predic- tion from the overall view to the technical process and further to the machining precedure is formed. The develop- ment and application of the corresponding prototype system are also illustrated in the paper.
