CHINA FOUNDRY Vol.6 No.1 Intelligent design of investment casting mold based on a hybrid reasoning method *Jiang Ruisong, Zhang Dinghua, Wang Wenhu, and Bu Kun (The Key Laboratory of Contemporary Design and Integrated Manufacturing, Ministry of Education, China; Northwestern Polytechnical University, Xi’an 710072, China) Abstract: A hybrid reasoning model was proposed in which CBR (case-based reasoning) was applied to the conceptual design and RBR (rule-based reasoning) was applied to the detailed design after research of the design process and domain knowledge of the aero-engine turbine blade investment casting mold design fi eld. In the conceptual design stage, the representation and retrieval technologies were researched which improve the retrieval effi ciency. Meanwhile, RBR was used to modify the retrieval result. The experimentation shows that the approach in this study can be used to obtain a more satisfactory design result.

In the traditional design one of
