In view of integrating the grinding field resources, grinding cloud platform refered to the ideas from cloud computing and cloud manufacturing, which integrated and used two categories of resources in grinding domain. The structure of grinding cloud platform was proposed, research of its key technologies was used to design the software structure.Using artificial intelligence,the application requirement model was proposed,the work flow and key algorithm of the system were designed. Designing and developing grinding cloud platform system composed of five software subsystems, including the SaaS service system, the PaaS service system, the IaaS-to-PaaS replication system among distributed heterogeneous database, the IaaS service system, the user login and register management system, which made the enterprises more convenient optimization in resource utilization. The grinding cloud platform was applied to practical productions, which improves the production efficiency effectively and reduces the production cost.
