Virtual Manufacturing Technology, Cnc Machining Simulation Studies And Implementation

To be developing in intense market competition, an enterprise should make a smart reaction to the change of market demand, make reasonable adjustment and re-scheme for the production in time. The quick development of computer and network technology provide a strong support achieving this goal. For these reasons, there have many new ideas and viewpoints in the 1990's, one of these is VM (Virtual Manufacturing). As a key of VMT, the simulation of NC (numerical control) cutting has an important status in this field. Moreover, it also has great value in application.This paper has adopted the dexel (depth element) representation solid model to discrete workpiece and cutting swept volume, after various NC simulation methods had been analyzed and compared. This method has reduced the complex degree in simulation greatly. On the base of these, the way to create solid and cutting tools modeling and display algorithm is corrected, and the efficiency is improved, which can reach the requirement of real-time simulation.Besides, the communication between system and external file has been discussed. All these has further improve the practicality and extendable of the system.
