Abstract：In view of the increasingly prominent bottlenecks in machining workshop for aerospace key parts under the new situation, such as the long cycle of process optimization, the low efficiency of resource allocation and the lack of means of quality assurance, the concept and methods of digital twins are introduced. Combined with the production and operation characteristics of machining workshop, the digital twin-based integration framework of aerospace key parts machining workshop is introduced. The ways of achieving the twin environment, the mapping hub and the enabling platform through twin data are explained. The optimization of the processing, the mixed-flow scheduling, as well as the quality diagnosis, prediction and control technology are discussed. The development and the integration of machining workshop digital twin system are also discussed so as to achieve the goal of dynamic iterative optimization and efficient collaborative management of the workshop.
