This paper presented a web-based virtual system to simulate forging operation. The system utilized simulation techniques of Finite Element Method (FEM) to analyze the forging process and Virtual Reality Modeling Language (VRML) to visualize the simulation results in the web. The analysis using FEM could show mechanical information such as stresses and deformation profiles of a specimen during forging process and the analysis results were transferred into virtual space using VRML. Since the forging machine and specimen were modeled using Java and VRML, the forging machine and analysis results were browsed and integrated on the web that is interfaced to users through EAI to show the whole forging simulation. The developed system realized the working environment virtually so that education and experiment could be performed effectively even on the PC.
