Abstract
In multi-stage manufacturing, it is essential to meet the quality requirements of form and precision for machining features. First, the classification of machining features was carried on, and the association relationships among machining features were defined. Then, machining features were mapped into the network nodes; and the association relationships among machining features were mapped into the network edges. A machining-feature-oriented initial evolution network was established and degree/betweeness were used to analyze the network performance. Finally, a case study was used to verify the proposed method. It is expected that this study can reveal the evolution rule of machining features in multi-stage manufacturing, and provide a theoretical support for identifying the key machining state parameters.
