Internet-based dimensional verification system for reverse engineering processes Sung-Chong Chung
The Journal of Mechanical Science and Technology, vol. 22, no. 7, pp.1259-1268, 2008
Abstract : This paper proposes a design methodology for a Web-based collaborative system applicable to reverse engineering
processes in a distributed environment. By using the developed system, design reviewers of new products are able to
confirm geometric shapes, inspect dimensional information of products through measured point data, and exchange
views with other design reviewers on the Web. In addition, it is applicable to verifying accuracy of production processes
by manufacturing engineers. Functional requirements for designing this Web-based dimensional verification
system are described in this paper. ActiveX-server architecture and OpenGL plug-in methods using ActiveX controls
realize the proposed system. In the developed system, visualization and dimensional inspection of the measured point
data are done directly on the Web; conversion of the point data into a CAD file or a VRML form is unnecessary. Dimensional
verification results and design modification ideas are uploaded to markups and/or XML files during collaboration
processes. Collaborators review the markup results created by others to produce a good design result on the Web.
The use of XML files allows information sharing on the Web to be independent of the platform of the developed system.
It is possible to diversify the information sharing capability among design collaborators. Validity and effectiveness
of the developed system has been confirmed by case studies.
