Detc Dfm Fixturenet Ii Interactive Redesign and Force Visualization on the Web

Digital communication over the Internet o ers advantages in terms of speed e ciency and automation Fortunately new geometric algorithms for design simulation and manufacturing have been developed and reported in the research literature Un fortunately the impact of these advances on the manufacturing community has been limited since implementations are di cult to port from one platform to another As an example of how the Web can facilitate interactive design we focus on one speci c application area modular x ture design We have substantially extended our previous xture design service FixtureNet Wagner et al and added in teractive tools to allow the user to build a deeper more intuitive understanding of the xtures found by FixtureNet The rst tool allows the user to simulate the e ects of forces applied to the part in the xture Our second tool enables the user to con sider changes to a part and verify in real time that the xture will still immobilize the modi ed part Our tools balance the tasks between the Web client and a central server performing fast user interactions in the client while running compute bound xture design jobs on the server The implementation of this work can be found on line at http riot ieor berkeley edu riot Applications
