Cloud manufacturing is emerging as a new manufacturing paradigm and an integrated technology.To adapt to the increasing challenges of the traditional manufacturing industry transforming toward service-oriented and innovative manufacturing,this paper proposes a product platform architecture based on cloud manufacturing.Firstly,a framework for the product platform for cloud manufacturing was built.The proposed architecture is composed of five layers:resource,cloud technology,cloud service,application,and user layers.Then,several key enabling technologies for forming the product platform were studied.Finally,the product platform for cloud manufacturing built by a company was taken as an application example to illustrate the architecture and functions of the system.The validity and superiority of the architecture were verified. 展开更多
