Abstract: To make full use of successful experiences and data accumulated in the application of high-speed machining practices, a case-based reasoning solution was put forward. The case description method and the attributes of local case similarity were studied. The local similarities of all attributes in problem description were classified as four types: the numerical, the independent, the enumerative, and the dependent. For these four types of local similarities, the four calculating means were provided correspondingly. Then, a composite similarity measure was presented, which was used to calculate the global similarity. Application results indicated that the case description and the similarity representation were feasible.

Key words: high-speed machining, case-based reasoning, case similarity, local similarity
