Improved Foundry Castings Utilizing CAD/CAM
Abstract
The CAD/Cam Casting process is being developed as an aid to casting engineers in designing better steel castings in a fraction of the time presently required. The computer routines incorporate drafting routines and computer assisted computations relative to heading and gating. Evaluation routines allow 2-D and 3-D heat flow analyses with a minimum of interaction from the user. In Phase I, computer software has been developed for working with two dimensional sections of arbitrary casting geometries. A routine for automatic mesh generation has been developed to handle a limited range of geometries. A 3-D finite element method heat flow simulation has been developed and applied to computation of the freezing pattern in stepped plate sand mold castings. The results of the computer simulations were compared with the results of thermal measurement in eight armor steel plate castings molded and poured under commercial conditions.
