Product-service system is a new globally optimized production system with high-degree integration of product and service, which is formed under the product lifecycle management thinking of manufacturing enterprises. This paper applies the modular design method in the development of CNC product-service system and studies the module division and configuration modeling method oriented to configuration design process. First, a service module division method based on design structure matrix is proposed, and the relationship of service activities is established through directed graph and the module division of service activities is determined by calculating reachable matrix. Next, the productservice integration strategy is analyzed, the product-service integration model is built, and the organic integration of product and services is achieved. Then, the meaning of configuration model of product-service system is introduced and the configuration model is established. At last, the economical turning center is selected as an example of CNC to implement the module division and configuration modeling of CNC product-service system and to verify the feasibility of proposed methods.

Product service system is a new kind of manufacturing system paradigm, in which product and service are highly integrated and fully optimized. Supplier involvement in product service system development will greatly raise the productivity. Service planning of product service system development with supplier involvement is one of the critical steps in product service system development. The necessity of product service system development with supplier involvement in CNC (Computer Numerical Control) machine tool product service system is decided by the complexity of CNC machine tool product service system. The process model of CNC machine tool product service system development with supplier involvement is built in this paper first. Then, the maintenance service model is determined based on service blueprint, and the maintenance service planning is implemented. Next, the mode of recycling and remanufacturing is analyzed. And the feasibility of recycling and remanufacturing of parts is judged finally.
