Abstract
The objective of this research is to propose an integrating modeling mechanism for three-dimensional casting process model (TDCPM) based on model-based definition (MBD). Firstly, the structure of the three-dimensional casting process model is put forward, and the TDCPM is comprised of three components: (1) process geometry model, (2) process information, and (3) process dimension information, building the relationship between the three components and give the planning procedure. Secondly, research the construction process of the casting part, gating system, and risering system; provide data structure, analysis method, and rebuilding mechanism of process dimension information; and introduce the casting process parameter and process planning history mechanism for TDCPM. Finally, a casting process planning system prototype is developed based on the proposed modeling mechanism.
