Research and Development on CAD/CAE Integration of Casting Process System Based on IGES Neutral File

Abstract

Nowadays, most 3D casting process CAD systems are developed based on second development tools of various 3D CAD systems. However the type and version escalation of various 3D CAD systems in foundry enterprises greatly limit the application of 3D casting process CAD systems. By the data exchange between the neutral file format of 3D geometric model, these problems can be well solved. In this study, by taking advantage of universal CAD data-exchange standard iges for data exchange, a practical 3D CAD system was developed based on opencascade geometry kernel. The system has the function of design and modeling of practical casting process such as part information extraction, parting surface, gating system, riser system and so on. Finally taking a steel casting for example, the casting process is exported in the file of stl and the simulation analysis is carried by intecast software which demonstrate the system based on iges neutral file can well support the integration of casting CAD and CAE.
