Intelligent design of investment casting mold for turbine blade based on hybrid reasoning method

A hybrid reasoning model was prompted in which CBR (case-based reasoning) was applied to conceptual design and RBR (rule-based reasoning) was applied to detailed design after research the design process and domain knowledge of investment casting mold design field for aero-engine turbine blade. In the conceptual design stage, the representation and retrieval technologies were researched which improve the retrieval efficiency; meanwhile, RBR was used to modify the retrieval result. The experimentation shows that the approach in this paper can expect to obtain a more satisfactory design result.
