Similar part intelligent retrieval method

Abstract

The invention discloses a similar part intelligent retrieval method, which comprises the steps of obtaining existing equipment database information, and obtaining a training part set by performing keyfeature extraction on parts in a database; performing feature recognition on the parts in the training set, and storing the obtained feature data as training data; performing feature recognition on all parts to be retrieved as a test part set, and storing the obtained feature data as test data; based on a Boolean operation method, performing similarity comparison classification on the features ofthe training set and the features of the test part set to obtain similar parts in the test part set. According to the method, from the angle of the parts, different part types are divided by distinguishing the characteristics of the parts from the parts, so that the part retrieval accuracy is improved, the production and manufacturing efficiency can be effectively improved, and the problems of how to quickly classify parts with large manufacturing equipment quantity and how to assist designers in completing product design in the mechanical product design process are solved.

Description

technical field [0001] The invention relates to the technical fields of computer-aided product design and intelligent manufacturing, in particular to an intelligent retrieval method for similar parts. Background technique [0002] As the market demand tends to be individualized and differentiated, the production mode of enterprises has also transitioned from a single-variety large-batch production mode to a multi-species and small-batch production mode. In order to adapt to changes in market demand, when faced with new orders, designers need auxiliary design tools to quickly and intelligently design mechanical products after the company formulates a reasonable production plan, and complete the intelligent classification of parts in mechanical product parts, plate parts, etc. Typesetting, profile parts statistics, material summary, purchase list summary, etc. provide convenience for production and manufacturing. Before that, a fast and effective retrieval method for similar p...
