Manufacturing resource sharing and collaboration is the core point of Manufacturing Grid (MG). In order to realize the resource sharing and collaboration among the heterogeneous and distributed manufacturing resources, a WSRF (Web Service Resource Framework)-based Resource Management System Framework of Manufacturing Grid, and Manufacturing Resource Encapsulation method are presented in this research. Manufacturing resources are encapsulated into WS-Resource structural entity entitled MG-Resources by stateful manufacturing resource encapsulation, web service encapsulation and interfaces construction, which explains the description, encapsulation, publication and invocation of MGResources. The encapsulation process shields complexity and diversities of manufacturing resources, thus implements the heterogeneous manufacturing resource sharing and collaboration in MG effect
