Manufacturing-oriented Multi-state Model for Aircraft Sheet Metal Parts

摘要

In order to define the intermediate workpiece information for the digital manufacturing of aircraft sheet metal parts, the Manufacturing-Oriented Multi-State Model for Sheet Metal Part (MOSS) is further studied. The model structure is constructed by the hierarchy of State, Feature, Element and Data (SFED). The hierarchy represents its content and relationship among its components in detail. The model application scheme shows that state information can be integrated with the systems of process planning and tool design, and the model provides a foundation for digital and intelligent manufacturing of aircraft sheet metal parts.
