Process planning service model design for cloud manufacturing

Aiming at the problem of complex parts machining process division and optimization, combined with the utility rules, process division and optimization constraints of current machine and cutting tools, the process planning service model for cloud manufacturing is proposed according to the idea of 'manufacturing as a service' in this paper. The model, based on cloud computing SaaS (software-as-a-service) service model and hybrid cloud deployment model, takes the principle of service-oriented, personalization and flexibility into account. Cloud-platform-based process service scene is designed, meanwhile the framework of information model for cloud process planning system is constructed. Resources such as process planning software, manufacturing workshop and process knowledge are encapsulated into cloud services, achieving the information integration of workshop resource service, cloud platform with machining process planning service. Finally, multi-users and multi-tasks parallel machining process planning and dynamic machining resources decision-making are realized.
