The invention relates to a multi-dimensional knowledge cloud coordination service method for complex curved surface processing and belongs to the technical field of knowledge service for a cloud manufacture process of complex curved surface parts. The execution process of the knowledge coordination service method is based on six layers of a service system, wherein a basic support layer is connected with the other five layers to provide network service and various kinds of application software and hardware resources for the other layers in the knowledge service process. The method provides effective and standard knowledge resource expression and storage modes, increases the processing efficiency and solves the problem of resource waste caused by improper technological planning or technical parameter setting. By packaging knowledge resources with specific functions into a knowledge cloud system with specific functions and building relevant functional components, the method can provide curved surface modeling design service, technological planning service, tool path calculation service, model machine trial-manufacture service, machine tool processing service and simulated analysis service and save processing time and information costs of specific function links.
