Abstract:

In the research and development of new aircraft engine, frequent aircraft engine design changes may lead to large amendment work quantity and lower design quality of machining fixture. To improve the response speed of machining fixture when aircraft engine design changes, a derivative design method is proposed for aircraft engine machining fixture design which is driven by the process model. The modeling approach is given after the characteristics of aircraft engine machining fixture are analyzed, then, the association between fixture and fixturing feature is confirmed, on this basis, the master tooling derivative model is established.Through designed the mapping algorithm for the fixturing features which are on the parts with similar structure, the fixturing feature of target process model and master tooling derivative model is associated automatically, and due to this fact, the design parameters linkage between target process model and master tooling derivative model are achieved. Accrording to the resource characteristics of different types of parts, the different derivative design strategies are proposed to improve the parts' reuse ration, Finally, the feasibility of this method are verified in a milling fixture design for aircraft engine casing.
