Abstract: In view of the limitation of trial cutting or manual inspection of the process planning validation of conventional numerical control, a new method of planning process simulation based on virtual reality was proposed. Firstly, the structure and implementation scheme of simulation system were given, and the simulation platform was established. Then, the movement behavior of machine tool was analyzed in details, an event handle model based on message response mechanism was proposed. Take tool change for example, the behavior module and the motion mode of related components were described. Researched and inferred the solving process of the curved surface of tool sweeping. The NC code compiler and cutting process simulation were expounded. Finally, the system was realized by means of using Visual C++6.0, OpenGL, Virtools and so on, It could verify the rationality of process planning and achieve the accurate assess.

Abstract: As an importantly functional and safe part of automobile, gasoline tank is gradually made by plastic instead of metal. To shorten the production cycle time and increase the output of plastic automobile gasoline tank, its cooling and solidification can be put on special fixture by wind or water after being taken from mold. An automatic plastic gasoline tank water-cooling equipment was designed with Solidworks software. The operation procedure was automatically controlled by program instead of manual work. By using PLC as control center and touch-screen as man-machine interface, the control system can be carried out to solve the difficulty of setting the technical parameters, such as water temperature and cooling timeless. The results show that the production output was increased and production quality was improved effectively.
