Abstract: Networked manufacture platforms are used due to their advantages, but new problems come out on how to integrate the existing networked manufacture platforms conveniently. Based on discussing the island problem in networked manufacture platforms and some current integration ways, a grid mode towards integrating networked manufacture platforms is proposed. The integration rules include invariability, expandability and usability. A virtual organization named networked manufactur platform federation is discussed from three aspects: the trust policy, the management pattern and the commercial style. The architecture of integration system is presented as well as four basic grid services, the federation management, the resource management, the authorization mapping and the cost transfer. The handling process of the new integration system is illustrated with an implemented case.
