The Research and Application of the CAD/CAE System of S.G. Iron Casting Process

Based on a commercial CAD modeling system Solid Edge, The author has developed a CAD system of casting process, which is specially designed for DISA process of the S.G. iron casting, and the system can realize three dimensional computer aided design. The solidification process of the modeling which includes processing information was simulated. During the solidification, the volume changes were simulated by using a method so-called Dynamic Expansion and Contraction Accumulation Method (DECAM). The optimization of process and the designing efficiency can be achieved by using this system.
