Sheet metal forming technology is key to aircraft manufacturing, and its informationization is the core to establish advanced digital sheet metal manufacturing technology. The connotation is analyzed, and the current research is overviewed. The approach to develop and apply key technology of sheet metal forming informationization is presented to manufacture the part efficiently and precisely. The engineering model should be defined orienting to forming process to drive the global process planning and local parameter prediction, tool design, NC programming for each working procedure, and then the total digital information definition, transfer and control mode is built. The knowledge from diverse source should be acquired, retained and integrated with current software to support the intelligent process, parameters and model definition, then the knowledge representation, management and utilization mode is built.
