Web-based Interference Verification System for Injection Mold Design

Abstract

This paper describes the development of a web-based interferences verification system in mold design processes. Although several commercial CAD systems offer interference verification functions, those systems are very expensive and inadequate to perform collaborative works over the Internet. In this paper, an efficient and precision hybrid interference verification algorithm for the web-based interference verification system is studied for injection mold design processes. In order to design a collaborative system over the distributed environment, the proposed system uses lightweight CAD files produced from the optimally transformed CAD data through ACIS kernel and InterOp. Collaborators related to the development of a new product are able to verify the interference verification over the Internet without commercial CAD systems. The system reduces production cost, errors and lead-time to the market. Validity of the developed system is confirmed through case studies.
