Manufacturing Feature Recognition Method for the Generation of Multiple Process Plans

摘要

In this paper, a manufacturing feature recognition method for the generation of multiple process plans is proposed. The feature recognition method is constructed in 2 phases. First, features are extracted using Extended Super Relation Graph (Extended SRG) Method. By using Extended SRG Method, interacting and overlapping features can be extracted in several different ways, corresponding with different kind of machining operations. In the second phase, the authors organize the extracted features into manufacturing feature sets using Feature Spatial Relation (FSR) Method. By organizing features into multiple manufacturing feature sets, the generation of multiple process plans is made possible, since each manufacturing feature set corresponds with different kind of process plans. In this paper, the authors describe the Extended SRG Method and FSR Method. The authors use a case study to clarify the effectiveness of these methods for the manufacturing feature sets creation.
