并行工程强调集成地、并行地设计产品及其相关过程,为CIMS的总体优化提供了新的思路和技术。本文首先分析并行设计的实质及实施并行设计的方法和关键技术,然后从面向制造的设计(DFM:Design for Manufacturing)及制造环境对产品设计(包括工艺设计)的约束来研究并行设计方法。通过开发制造环境建模工具,建立制造环境能力库,实现产品设计可制造性评价的信息反馈,从而实现并行设计。
Concurrent engineering emphasizes the integrated and parallel design of products and their related processes, providing new ideas and techniques for the overall optimization of CIMS. This paper first analyzes the essence of parallel design and the methods and key technologies of parallel design, and then studies the parallel design method from the constraints of DFM (Design for Manufacturing) and manufacturing environment (including process design). Through the development of manufacturing environment modeling tools, the establishment of a database of manufacturing environment capabilities to achieve product design manufacturability evaluation of the feedback, in order to achieve parallel design.
