【Abstract】 Purpose.To our best knowledge,we are the first in China to offer an instance base for CAD system of investment casting mould used in gas turbine blade manufacture;such an instance base,we hope,can meet the urgent need of PRC gas turbine manufacturers for full exploitation of past experience in investment casting mould design proven to be successful.In the full paper,we explain in much detail the above-mentioned first Chinese instance base;here we just list the five topics discussed in our detailed explanation:(1) case-based reasoning(CBR) for CAD system of investment casting mould used in gas turbine blade manufacture;(2) the description of each instance in instance base for CAD system of investment casting mould used in gas turbine blade manufacture;(3) the organization of all instances;(4) the storage of all instances;(5) the searching for useful instances.更多还原
