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.
