Abstract
In order to maintain the topological relations for the elements of casting process model and rebuild the casting process correctly when process parameters is changed, the topological entities naming method is used in this paper. Firstly, topological entities naming method, including naming rule for entity ID, Geometry_Name, and Process_Name, is proposed, and the mapping strategy between topological entity name and process information is established. Then, the geometry modeling method for casting process is studied in three steps: (1) process parameter setting method for gating and riser system; (2) parametric modeling procedure for gating and riser system; (3) the 3D process dimension design procedure for gating and riser system. Thirdly, the reconstruction method for parametric casting process model based on topological entity identification is given. A prototype of 3D casting process planning system is developed, and the reconstruction method is tested by an example part.
