Intelligent Control System of Deep Drawing for Rectangular Box

Based on the research achievements of intelligent deep drawing for an axis-symmetric part, the key technologies of intelligent deep drawing for a rectangular box are discussed in this paper. Signal monitoring and control can be realized nicely in the process of deep drawing by applying the technology of LabVIEW VI (virtual instrument). Real-time identification of material properties can be achieved with artificial neural network, and the network error is stepped downward to 2% by the application of LM (Levenberg-Marquarat) optimization algorithm. The real time predication of optimized processing parameters comes true based on predictive principle, in which the error of predication is within 10%. Based on the concept of real time monitoring, real time identifying, real time predicating and real time controlling, a control system of intelligent deep drawing for rectangular box has been developed recently.
