The design of forming processes, particularly those involving aluminum alloys, is the focus of the research of this collaborative project between the University and industry. The work will attempt to utilize the complementary aspects of backward-tracing algorithms and the ideal forming theory based on the minimum plastic work path concepts. The design sensitivity calculations will be used as the vehicle for relating one to the other. A unified manufacturing design strategy that attempts to optimize simultaneously the geometric and material specifications for the preform, as well as the temporal and spatial characteristics of the process parameters, is the immediate goal of this research. The design strategy will be applied to the design of real-life forming processes, and the results will be experimentally verified. The design strategy will eventually be extended to include issues of product design as well. This will allow the realization of an long-term goal of concurrent, rather than sequential, design of formed products and forming processes.

成形工艺的设计，特别是涉及铝合金的成形工艺设计，是该校与产业界合作项目的研究重点。这项工作将试图利用反向跟踪算法和基于最小塑性加工路径概念的理想成形理论的互补方面。设计灵敏度计算将被用作将两者联系起来的工具。一个统一的制造设计策略，试图同时优化预制件的几何和材料规格，以及工艺参数的时间和空间特性，是本研究的直接目标。将该设计策略应用于实际成形工艺的设计，并对设计结果进行了实验验证。设计策略最终将扩展到包括产品设计的问题。这将允许实现形成的产品和形成过程的并行设计而不是顺序设计的长期目标。
