The title panel information in engineering drawings is the important data source for product data management (PDM). Firstly, the data structure of title panel and bill of material (BOM) information in engineering drawing was analyzed, and the collected concourse based on the describing information cell was put forward. Then the text-objects and line-objects within the collection concourse were handled...
In this paper, an important method for computing the tool-path, and constructing the offset curves of pocket boundary generates its tool-path planning is the Contour-parallel strategy. But it is very difficult for the judgment and disposal of loop. The main disfigurement of the algorithm in the contour-parallel calculation includes to judge and dispose the linking of offset curves, and to take out...
A customer's requirement (CR)-oriented study of product configuration management (PCM) information model based on PFSC for aeronautical Subcontract production is brought forward. And a uniform product configuration model is formulated. Also, a PCT-based information model of PCM by self-organizing mapping, which in the relative matrix of customer's requirement characteristics and the functions principle...
In this paper, the main problem on PCM of aero subcontract production (SP) is indicated, and a customer's requirement (CR)-oriented theoretical research on PCM info modeling based on PFSC are brought forward. Firstly, the concept of CR domain and feature expressive domain based on the theory of product family configuration model is introduced, which provides the method for the mapping and transformation...
The distributed product data management (DPDM) is the key effectively of the remote collaborative designing and manufacturing for complex product. A study project on DPDM and consistency control techniques based on collaborative service platform (CSP) in aero subcontract production (aero-SP) is put forwarded. First, in order to settle the problem of data exchange and share, collaborative workflow...
