Virtual Manufacturing Technology Overview (2)
1) Virtual processing analysis tools are not yet abundant. Although there are many commercial softwares that can be evaluated for processability, VMs need to research and develop a large number of virtual machining analysis tools, such as machining process simulation systems with cutting force analysis functions, and the impact of cutting processes on product quality (including Residual stress, cutting temperature field, etc.) and method of estimating part manufacturing costs; 2) Research on object-oriented integrated assembly modeling. International research on virtual assembly is not uncommon, but in assembly modeling, object-oriented assembly modeling will be a trend, and integration is an inevitable trend of assembly modeling. 3) Further research on assembly process planning. The assembly process planning is still in the research stage. The limitations are mainly manifested in four aspects: combined explosion or a large number of interactive questions and answers, which limits the number of components of the target product; only considering the translation along the coordinate axis direction, the assembly movement mode is too simple; Emphasis on geometric calculation, the use of engineering semantic knowledge needs to be strengthened; the selection criteria of assembly sequence are not extensive and uniform; 4) Basic theoretical research on virtual assembly. There is still no theoretical basis for tolerance analysis and synthesis technology in virtual assembly. Existing tolerance analysis and integrated software still have many problems in model generation and support for ISO tolerance standards and support for geometric tolerances. the study; 5) Research on virtual test technology. Virtual testing is a key part of the successful use of virtual product development technology, because under the existing technical conditions, the unit model is indispensable for the product, process or system, testing and verification. Testing and verification also have a significant impact on the efficiency of virtual product development. VMT is a higher stage of CAD/CAE/CAM technology development, and is also a product of computer graphics technology and simulation technology development. It has important research and application significance for product development. Since the functions of commercial VMT related software and hardware systems are still limited and expensive, developing a virtual manufacturing system with low cost and complete functions should become one of the important contents of VMT development. The developed content includes anthropomorphic user interface. Event-based real-time simulation engine, virtual peripheral hardware interface, virtual simulation language, data universal conversion interface with traditional CAD software, various databases and tool libraries. 2 Current research hotspots of VM Despite the tremendous achievements in the application of virtual reality technology in manufacturing However, there are still many problems to be solved. The hot spots in today's society are: a) Integration and collaboration of various resources, including the effective organization of human resources and existing knowledge and technical resources, enabling all experts to effectively cooperate with existing conditions, methods and tools to conduct VM research and development in manufacturing ; b) sharing and inheritance and reusability of model data in virtual product design, virtual process design, virtual production and processing, virtual assembly, virtual enterprise and virtual equipment, raw materials and product supply chain; c) collisions in the virtual assembly and collision deformation of the parts and force feedback problems. 3 Conclusion VMT is one of the important technologies for information manufacturing. Implementing VM requires strong technical support. The application of VMT should be combined with the characteristics of China's manufacturing industry itself. On the basis of absorbing foreign mature experience, we will boldly innovate and form characteristic development. It can be predicted that with the study of VMT in China, the exploration of people. Its wide application has not been far behind, and will eventually become the only way for a modern, information-based manufacturing enterprise.
