The service-oriented manufacturing paradigm is a new advanced manufacturing paradigm. In order to support it, a cloud service resource sharing model for service-oriented manufacturing is proposed. Based on the analysis of the features of manufacturing resource under the service-oriented manufacturing, concepts of cloud service resource and cloud service resource pool are defined, then service-oriented manufacturing resource and service-oriented process are realized through resource unified modeling, resource matching and resource optimization. The cloud service resources are classified by ontology method, then semantic and vector distance algorithm are adopted for intelligent search. Finally, service mode and realization technology are verified through a PLM soft resource application case. Theoretical analysis and experimental results suggest that the proposed resource service sharing model can meet the requirements of the service-oriented manufacturing.
