【Abstract】 Although the study of casting technological GAD is widespread day by day , there are still many problems being on the initial research. Of them, one of the most important problems focused on is to build up the simplified geometrical models. Getting a good solution of it is the prerequisite to make the overall design of casting technological CAD system. Especially, the consideration of it is more necessary, when developing such a CAD software under a microcomputer environment. On basis of the author’s experiences in designing the casting technological CAD software, this paper presents the impoitance, principle, method and application of simplifying the geometrical model.更多还原
