Research and Development of Casting Process CAD System for Steel Casting based on OpenCASCADE and wxWidgets

摘要

With the development of computer technology, the casting process CAD system has become the main way of casting process design for process designers. Most of these systems are developed based on second development tools of commercial 3D CAD systems. Due to the version escalation of commercial 3D CAD systems and confidentiality and consistency of data in foundry enterprises, the application of casting process CAD systems are greatly limited. To handle these problems, this paper puts forward the casting process CAD system for steel casting based on OpenCASCADE and wxWidgets. The framework of casting CAD system is constructed by the 3D geometric modeling kernel (OpenCASCADE) and the interface design platform (wxWidgets). The system has the function of practical casting process design and modeling, including part information extraction, gating system, chill system and riser system and so forth. Finally, taking the articulation piece for example, the casting can be designed by the system. It shows that the system resolves the above difficulties and improves the speed of casting process design and the ability of casting information exchange.
