Abstract

The invention discloses a manufacturing industry workshop process planning system based on digital twinning, and relates to the field of workshop process planning. The digital twinning-based manufacturing workshop process planning system comprises theoretical preparation, process planning, a virtual space and a physical space, wherein the process planning is performed through the theoretical preparation, the virtual space and the physical space are established according to the process planning, the physical space is fed back to the virtual space in real time, and the virtual space performs process change on the physical space. The virtual space supports collaborative engineering, the physical space supports parallel engineering, the collaborative engineering and the parallel engineering realize information physical fusion, and a digital process planning system is established. According to the manufacturing workshop process planning system based on digital twinning, a simulation model of the virtual space and an entity of the physical space can be mutually mapped, seamless connection from design data to a process is achieved, the consistency of manufacturing and design data is improved through implementation of a three-dimensional process system, and efficiency and quality are improved.

Description

technical field [0001] The invention relates to the technical field of workshop process planning, in particular to a digital twin-based manufacturing workshop process planning system. Background technique [0002] Today's domestic manufacturing industry has improved product design and development capabilities (CAD) and production and manufacturing capabilities (CAM) through computer-aided manufacturing systems and advanced modern production equipment. However, the manufacturing capabilities and related process levels (CAPP) and The ability to adjust production has not improved accordingly. As an emerging manufacturing technology, digital twins create a virtual model of a physical entity digitally, using data to simulate the behavior of a physical entity in a real environment. Through the construction of a production line process planning system simulation environment, it can Incorporate the most important production preparation, process planning, ergonomics, and equipment ma...

AI Technical Summary

Problems solved by technology

[0003] The practical application of domestic digital twin research is still insufficient. There are relatively few studies on the integration of complex product design and manufacturing based on digital twins. Only in terms of process information transmission and expression, my country has not yet gotten rid of the Soviet-style two-dimensional table method. , technology and manufacturing resources are linked together, and the factory is not actually mapped, and the layout of the factory is inseparable from production capacity and performance. Process requirements. After the process arrives at the site, it still needs to be optimized. This will cause the process to be repeated repeatedly, and the linkage of the four major data cannot be realized. The link lacks the integrated holographic process technology, and the process stage cannot fully realize the impact on subsequent manufacturing. The analysis and evaluation of the process plan, the domestic digital process management has not formed a common chain, only in a certain information technology point in the process stage can be equivalent to foreign capabilities, in the general transfer of the same data source with a single information structure, it is obvious Lack of integration concept, poor unity in overall information source management, not to mention the proposed concept of digital factory

my country's 3D digital R&D process products are poor in versatility and practicability, and cannot well cover most industry characteristics. Therefore, it must be realized through secondary development during the implementation process, which has certain limitations; because domestic software manufacturers do not With 3D design software capabilities, it can only be integrated with other upstream and downstream 3D mainstream software, and cannot achieve true integration of design, process, and manufacturing
