摘要：

In order to develop a special CAD system for tube cold drawing, the practical data and experience have been put into consideration as usual, and with the help of MARC software, the finite element simulations have been carried out over 1 000 times under widely possible processing parameters. After being analyzed and modeled, the results of the simulations are directly introduced into the CAD system, so that the CAD is capable of helping tube manufacturers notonly arrange their drawing procedure system easily and efficiently, but also optimize their drawing processes in several aspects, such as drawing force, die geometry, plug geometry, distribution of reduction, accuracy of tube dimension, consumption of deforming work, quality of tube, and so on. The optimized cold drawing procedures are able to lower production cost by 1 %-5 % in average.
