Research Initiation: CAD System for Casting Process

金属铸造业是我国最重要的行业之一。如果有可能从设计者心目中存在的精加工铸件开始，并使用计算机辅助设计(CAD)模块和数控机床来设计和制造制造铸件所需的图案，它可能会得到极大的加强。这种能力的开发分两个阶段进行：开发设计图案的CAD系统，开发设计模具的CAD系统，完成熔融金属流动所需的通道(浇口和立管)。CAD系统将基于一种名为Romulus的几何建模系统。根据铸造人员熟知的经验法则，将创建一个“专家系统”。

The metal casting industry is one of the most important in the country. It could be strengthened significantly if it were possible to start with a finish-machined casting as it exists in the mind's eye of the designer and, using computer-aided design (CAD) modules and numerically controlled machine tools, to design and fabricate the pattern required to make the casting. Development of this capability is undertaken in a two-phase approach: development of a CAD system to design patterns, and development of a CAD system to design molds, complete with the channels (gates and risers) required for flow of the molten metal. The CAD systems will be based on a geometric modeling system known as ROMULUS. An "expert system" will be created, based on rules of thumb well known to foundrymen.
