Technology is an important link to endow the soul of the products developed and designed. Promoting the application of digital technology and covering the whole life cycle of product design, process and manufacturing is a key point to realize intelligent manufacturing. Through the construction of process digital information platform, the data flow between design, process and manufacturing will be open to achieve efficient collaboration between upstream and downstream. Through the deepening application of digital process, the process consistency will be 100%, 20% problems will be verified and found in the early planning stage, and the production preparation cycle of products will be shortened by 20-30%.

2.1 Early stage of digital process platform construction

Complete the basic function module development and application. Product preparation management in accordance with APQP control, systematic control of project progress and delivery; BOM and process management, to achieve timely and accurate data, improve process consistency and standardization; Change management implements forward and reverse closed-loop management to improve the quality of change execution; Realize process resource management and control, realize knowledge accumulation, sharing and reuse.

2.2 Process digitization platform construction stage

Realize process innovation management: through process simulation technology, realize 3D digital process planning and verification, and carry out virtual simulation and evaluation of process rationality; Realize 3D process in the factory, improve the visibility of the process; Through production line simulation technology, simulation, optimization and management of production line equipment, logistics, process, beat, personnel, production process, etc.

2.3 Later stage of process digitization platform construction

Realize the deep application of process digital technology: through digital mapping technology, realize the linkage between actual production and virtual production, which can timely correct the deviation and problems in production and realize more scientific and intelligent production. Strengthen the construction of digital technology team, set up a special project team to take charge of technical research and system construction, and promote the work of digital process upgrading.

Establish digital standard system and business process, and formulate perfect digital process according to data flow, business flow transmission characteristics and upstream and downstream relationship, so as to realize management innovation to promote technology innovation and technology innovation to promote management innovation. Strengthen digital infrastructure and design and manufacturing AIDS development. From the software foundation environment, database support platform, network information environment, information security system and other basic aspects of investment and construction.

2.4 Application of simulation system

Combined with production line numerical model, logistics simulation, etc., to realize production line simulation,  verification, optimization and management of production line equipment, logistics, process, beat, personnel, production process, etc. Through digital mapping technology, the linkage between actual production and virtual production can be realized. When there is a problem in the production line, it can be reported to the virtual system in real time. After the virtual system verification, the virtual parameters can be changed to realize the synchronous change of the production line, so that the deviations and problems in production can be corrected in time, and the production can be more scientific and intelligent.

Through the deep integration with MES, ERP, process equipment, process resources and other workshop systems, the research and application of digital workshop technology is realized, which lays the foundation for the realization of intelligent workshop and production line big data analysis.
