Abstract: High performance manufacturing, which is from manufacturing based on geometric accuracy up to manufacturing based on the precise guarantee of product performance, is of great significance to the development of the national equipment industry as the engine to promote the upgrading of equipment manufacturing industry and the banner to lead the upgrading of traditional manufacturing concepts in China. High performance manufacturing theory states that the conventional equipment manufacturing process has formed a strict upstream and downstream relationship between design, manufacturing, operation, promoting the ability of collaboration on multiple tasks and improving the efficiency of equipment manufacturing, to a certain extent. However, the fact cannot be ignored is that this one-way serial mode of design and manufacturing artificially severs the coupling between these two processes. While improving the manufacturing efficiency, it also inevitably restricts the further improvement of high-end equipment performance. As a vital part of the high performance theory, a discussion of the coupling between design and manufacturing is developed. For the first time, the Karush-Kuhn-Tucker optimality conditions are used to quantitatively reveal, from a mathematical perspective, the root causes of "non-collaboration" in the traditional design and manufacturing, and to these deficiencies, solutions for serial, parallel and cyclical modes are presented. It provides a theoretical and technical reference for breaking the bottleneck of high performance manufacturing of high-end equipment/components and further promoting the development of high performance manufacturing of high-end equipment in China.

Key words: high-end equipment/component, high performance manufacturing, collaboration of design and manufacturing, parallel mode, cyclical mode
