Dynamic three-dimensional shape simulated has been studied for the gearbox production line in the virtual machinery environment. Dynamic three -dimensional shape's model of design are put forward, it uses of the model of manufacturing to machine parts for the Virtual prototype and simplifies designing process of prototype. It effectually combines CAD/CAM and the technological plan layout DSS with Dynamic three -dimensional shape simulated. It has described process of produce design and manufacturing in the audio-visual and integrated. The result of the research shows that dynamic three -dimens...
