Synthesis of the web-based CAD viewer for interference verification of injection moulds

초록

This paper describes the development of a web-based interference examination system in mould design processes. Although several commercial computer-aided design (CAD) systems offer interference inspection functions, those systems are very expensive and inadequate to perform collaborative works over the Internet. In this paper an efficient and precise hybrid interference examination algorithm applicable to multilevel assemblies is studied for injection mould design processes. In order to design a collaborative system over the distributed environment, lightweight CAD files produced from the optimally transformed CAD data through ACIS kernel and InterOp are applied to develop a web-based interference verification system. Collaborators related to the development of a new product can verify the interference over the Internet without commercial CAD systems. The system reduces production cost, errors and lead-time to the market. The validity of the developed system is confirmed through case studies.
