To solve the problem of virtualized encapsulation of processing equipment resources in cloud manufacturing,an open and flexible processing equipment resource model was established.On the basis of analyzing the connotation,classification and characteristics of manufacturing resources,the characteristics of processing equipment resources were analyzed first.Then combined with semantic knowledge and WEB technology,the resource model of processing equipment was established.The semantic description method of processing equipment resources was given,and the semantic description template was established.Finally,the cloud manufacturing resource matching process was described in detail.The research would provide an important basis and condition for resource management of cloud manufacturing platform.
