      Abstract:An approach to a solution of sequencing machining operation on a machining center was proposed. The artificial neutral networks(ANN) was used to choose machining methods for each feature,the methods were combined to be possible machining schemes,and then genetic algorithm was applied to operation sequencing for the possible machining schemes with the minimization of machine idle times as objective function.The correlative machining features were clustered as a feature for sequencing to simplify the computation,and then the tools path was optimized for the feature with shortest idle path as object.A test part was selected to demonstrate the mechanism of this algorithm. The result shows that the method can improve operation optimization sequencing capability of process system.

      Abstract:An approach to a solution of sequencing machining operation on a machining center was proposed. The ANN is used to choose machining methods for each feature, the methods are combined to be possible machining schemas, and then genetic algorithm was applied to operation sequencing for the possible machining schemas taking minimization of machine idle times as objective function. To reduce the compute complexity, the correlative machining features are clustered as a feature for sequencing, and then the tools path is optimized for the feature with shortest idle path as object. A test part was selected to demonstrate the mechanism of this algorithm. The result shows that the method can improve operation optimization sequencing capability of process system.
