Abstract: To solve the problem of transforming the production data into knowledge in knowledge acquisition,through comparative analysis on composition structure of test data and knowledge for flange springback in rubber pad forming of frame rib parts,a knowledge transformation process model included data conversion,relational mapping,state determination and knowledge fusion was presented.To assure the uniqueness and consistency of knowledge in knowledge base,similarity measurement based on grey coefficient was employed to detect the redundancy and conflict.The prototype system for knowledge transformation was developed to verify the usefulness of the proposed approach.

Key words: knowledge representation, knowledge transformation, similarity measurement, conflict resolution
