The ETO product’s modularity manufacture needs the ETO product’s modular design as a foundation. By fully distinguishing and exploiting the geometry similarity, the structure similarity, the function similarity and the process similarity of the multi-ETO products, using the methods of standardization, modularization and serialization, the ETO products as well as the corresponding manufacture systems are modularized. In view of various standard components and parts produced by the modular design and manufacture, the products needed for the customers are directly assembled using a set of the advanced operation flow suitable for the modular assembly, and selecting the appropriate standard parts. Thus the production cost, the assembly cost as well as the inventory cost and so on are reduced. The modular manufacture is using the modular technology in the manufacture process to form the overall integrated production and assembly system of the components, and to recompose the manufacture process promptly according to the specific production. This paper proposed the optimization method of production organization, established the CAPP system’s architecture based on the modularity technique supporting the ETO product and developed the cooperative CAPP platform of the multi-functional hydraulic lift machinery.
