Technical state linkage method in product manufacturing process

Abstract

The invention relates to a technical state linkage method in a product manufacturing process. The method comprises the following steps: firstly, designing an interactive integrated interface between aproduct design system and a three-dimensional process design system; establishing a three-dimensional design model of a product based on a product design system, and transmitting an EBOM, a model anda design file in a part model to a three-dimensional process design system through an integrated interface; and when the product data of the product design system is changed, updating the part modelin time, and meanwhile, dynamically updating the three-dimensional process in the three-dimensional process design system through the integrated interface. According to the invention, the three-dimensional model is used as an information carrier, and reasonable data organization is carried out on the three-dimensional model to realize linkage under the technical state change of design data, process data and manufacturing data. The process design period of the product is shortened, the process quality is improved, the loss and cost caused by design errors are greatly reduced, and the process design efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of product manufacturing, and in particular relates to a technical state linkage method in the product manufacturing process. Background technique [0002] Process design is in the middle of product design and manufacturing, and it is a key step in the preparation of production technology. With the development of digital manufacturing technology, MBD model-based design has been widely carried out at the design level. How to do a good job in 3D production at the process level and how to do a good job in 3D process design based on a unified data source are imminent. Although the current weapons and equipment products have partially realized the model-based process design mode, which shortens the process design time, reduces labor intensity, improves the quality of process documents, and shortens the production preparation cycle, but because designers and craftsmen use different The work platform carries out product des...

Problems solved by technology

Although the current weapons and equipment products have partially realized the model-based process design mode, which shortens the process design time, reduces labor intensity, improves the quality of process documents, and shortens the production preparation cycle, but because designers and craftsmen use different The work platform carries out product design and process design. The design model is often manually imported by the craftsman, which cannot guarantee the correctness and timeliness of the product model data. It is not related to the product design. The product model data source is not unique, and the process compilation cannot be automatically inherited. Relevant design information, which is an informal process design

At the same time, the product needs to be constantly changed in the design, process, and manufacturing links. The information communication between the 3D process design system and the design system is not smooth, and the downstream MES and other tool software cannot automatically inherit the relevant process data, resulting in the interruption of data information. make work inefficient
