Development of Knowledge Based Process Planning System for Non-Symmetrical Sheet Metal Forming Processes

板材和汽车行业需要以灵活性和成本效益不断提高其战略竞争优势，以在不断变化的世界经济中保持竞争力。为实现这一目标，本研究的主要目标是设计和开发一个基于知识的非对称拉深工艺设计系统。通过研究工艺变量对板材拉深性能的影响，通过必要的试验和有限元分析获得相关的工艺信息，以及通过从多个板材制造行业中挑选领域专家获取工艺信息来开发规则库，将实现这一目标。

Sheet metal and automotive industries need to continually improve their strategic competitive advantages with flexibility and cost-effectiveness to remain competitive in a changing world economy. In order to achieve this, the primary objective in the proposed research is to design and develop a knowledge-based process planning system for non-symmetrical products produced by deep drawing processes. This objective will be achieved by investigating the effect of process variable on drawability of sheet material, by obtaining relevant process information through necessary experimentation and finite element analysis and by development of a rule base by acquiring process information from domain experts selected from number of sheet metal manufacturing industries.
