Abstract
Blades of aviation engine are usually composed of complex three dimensional twisted surfaces that request high geometrical precision. Their machining is very difficult. Hence, how to reuse successful machining technics becomes an important and effective measure to improve blade machining quality. Machining parameter optimization for blades of aviation engine based on CBR and database is discussed in the paper. The system architecture and workflow are presented. Machining parameter database based on CBR consists of a case library and a machining database. Both of them can not only run independently, but also be integrated through application interface. Case representation includes two aspects, namely problem and objective description and solution scheme. Similarity ratio calculation is divided into local similarity ratio and integral similarity ratio. Through system development, it is proven to be feasible that machining parameter optimal selection is realized based on CBR and database.
