| Abstract: | Virtual reality (VR),as a new technology,is integrated with software systems for engineering,design,and manufacturing.Visual interactive simulation system based on VR for plastic injection molding was proposed and completed.Key techniques (FEA,Delaunay Triangulation,movement simulating approach) of the system were described in detail.The overall system is a new powerful approach for highly relevant industrial application of VPIM which focuses on the construction and assessment of alternate manufacturing sequences and mould design in an early design stage.Improvement of their design and manufacturing process will lead to savings in better design and reduce development time and cost. |
