Stimulation Generation Method of STEP-NC Process Routing Based on FBM Constrained Relationship

Abstract

Abstract. The excitation selection sort method of manufacturing feature was proposed based on the characteristics oriented to manufacturing feature of STEP-NC to realize the process route planning of STEP-NC. First, match the recognizing manufacturing feature, the manufacturing feature with multi machining operation was disintegrated in order that every manufacturing feature has only a processing operation. Then, the rationality constraint problems of machining operation was translated into the processing order problem of manufacturing feature, and the optimal constraint problem of machining operation was translated into the corresponding manufacture feature set. The process route was generated by the operations of excitation, selection, deletion and transfer for the feature of different manufacture feature set. The last, the feasibility and effectiveness of the process route excitation generation method was verified by an example, and show that this method was better solved the problems of process rules and the representation of knowledge.
