Fault analysis and maintenance embodiment of hydraulic apparatus in the lathe;

Frist,this paper analyzed traditional case retrieval method and proposed to introduce case adaptation knowledge to its retrieval phase in order to guide retrieval orientation and obtain similar and adaptable good cases that can be reused and easily adapted.

In order to improve the degree of automation of design of machine product, study a key technology of the conceptual design based on CBR: case adaptation.

Case modification technique in engineering design based on genetic algorithm;
