Abstract：

For the problems of inadequate metal forming property parameters and technique knowledge and lacking an unite management system during manufacturing aerospace sheet metal presently, the data were obtained by the tests of blank forming property and the technique knowledge coming from six kinds of processes was summed up. The information was input to the system of aerospace sheet metal property parameters and technique knowledge developed by Visual Studio and Oracla, which includes the database of property parameters, the knowledgebase of sheet metal techniques and the management system. The database can provide parameters for finite element simulation analysis，assist engineers in manufacturability examination, technical design, equipment design and disfigurement diagnosis，support all the digital producing cycle of sheet metal parts, shorten the period, and save cost of airplane manufacture.
