SBIR Phase I: An Expert System for Design of Net Shape Forming Processes

净成形模具的设计和制造是一项漫长、复杂和昂贵的工作。研究探讨了生产专家系统的可行性，供产品和工艺设计人员在评估和选择生产工艺时使用。这些过程需要详细地了解和控制几个相互作用的现象：金属流动、热传递和摩擦，在三维结构--工具内。由于这些现象的复杂性，工具的设计在一定程度上是基于专家头脑中的规则，以及对分析模型的影响。这个项目的方法是将这两种类型的知识嵌入到微型计算机中，以一种小型制造公司可以使用的形式。

Design and fabrication of tooling for net shape forming processes is a lengthy, complex and expensive undertaking. Research addresses feasibility of producing an expert system for use by product and process designers in evaluating and selecting production processes. These processes require detailed understanding and control of several interacting phenomena: metal flow, heat transfer, and friction, within a three dimensional structure--the tooling. Because of the complexity of these phenomena the design of the tooling is based in part on rules in the minds of experts, and impact on analytical models. The approach in this project is to embed both types of knowledge in a microcomputer, in a form usable by small manufacturing firms.
