Embodiment

[0019] 1. Production data modeling

[0020] Download the part geometry information and product structure information of the left front door of the car from the enterprise website KVS through the data interface conversion tool Kate. Kate uses the imported product structure data to find the corresponding part information on the KVS website and download it. When downloading, the geometric information of the part is automatically converted into a .CO file format that the system can recognize. After the file is downloaded, use the automatic import function of Kate to import the downloaded part information into the body-in-white product data management and process planning system. The generated product engineering model contains the corresponding part data information, which consists of items such as synthesis, physical attributes, cost, manufacturing features, operations, resources, and additional attributes.

[0021] Each node of the product engineering model represents a resour...

Abstract

it is a blank car product process digit design method, which comprises the product data module establishing, process designing, product line simulation and optimization and comprises the following steps: to input the blank car information into the product data module establishing system and establish one product engineer module; to design the working poison , sequence and resources on the whole product line through process sub-system; to make the simulation and optimization and adjusting of the processes of wielding, glue-coating and frame-dissembling on the whole product line through product line simulation and optimization system.

Description

technical field [0001] The invention relates to a virtual manufacturing method for industrial production, in particular to a digital design method for a body-in-white production line process, which is used in automobile production. Background technique [0002] With the increasing internationalization of the automobile market, more and more international advanced automobile manufacturing enterprises have entered the domestic market, and the market competition has greatly intensified. In order to win customers and win the market, automobile manufacturers have accelerated the pace of launching new models, and the speed of new product development has become one of the key competitiveness of automobile manufacturing enterprises. The car body is an important part of the car, the main part in the change of the car model, and the carrier of the whole car parts. Its manufacturing cost accounts for about 40% to 60% of the whole car. The car body is a complex system. Its parts are no...
