摘要

A new in-process identification method of material properties and lubrication condition in the deep-drawing process of anisotropic sheet metals is proposed and applied to the adaptive process control ofthe blank holding force (BHF). The method is based on a combination model of artificial neuralnetwork (ANN) and elastoplastic theory. Three delegated plastic deformation properties, i.e. n value,F value and plastic anisotropic coefficient r, were identified using the measured process information atthe beginning of the process by means of ANN. The friction coefficientμ and the optimal BHFcontrol path were then calculated from the theoretical model. Furthermore, the friction coefficientwas monitored during the entire process, and a closed-loop control was applied to modify the BHFpath corresponding to the frictional variation. Experimental results show that the artificial intelligence(AI) control system can cover a wide range of both materials and influential parameters, such asfriction and ambient temperature automatically. It is confirmed that the newly developed system is avalid alternative for the quick responsible control system with high flexibility.
