Research on estimation of energy consumption in machining process based on CBR

The estimate result of energy consumption in machining process could be used in process planning evaluation, workshop scheduling and fine energy management. In the layer of process planning, a process model of energy consumption prediction based on case-based reasoning was presented, in view of the characteristics of energy consumption in discrete manufactures, the case retrieval process and the method of energy consumption result reuse were proposed. The machining process of turbine rotor was taken as example to verify the feasibility and validity of the approach finally.
