Part manufacturing model framework oriented to process chain

Aiming to extend part design model for process,the concept of part manufacturing model was presented based on analyzing the part process chain.The framework of part manufacturing model was constructed with an example of complex aircraft integral panel part.The composition of part manufacturing model was presented.Part state in process was regarded as the component of part manufacturing model,and it was divided into model for workpiece and model for process.The information hierarchical structure of the model was set up and the method to represent model information which was oriented to integrated manufacturing was provided.The data organization structure based on shape control node was described.The definition process of the part manufacturing model was described based on Petri net.It was indicated that digital definition,management and integrated application methods could be further developed based on this framework to realize precise,rapid and economic part manufacturing.
