Abstract：

Precision forging is a kind of near net forming or net forming technology, and the demands from industry push forward the development of the technology. Therefore, the precision forging process, forging die, forging of complex part and the application of numerical simulation in the precision forging were introduced respectivety. For the forging process, some new precision forging processes such as combined warm and cold forging, divided flow forging, flow control forming, forging-stamping compound forming and enclosed die forging were generated, and for the die structure design, some novel methods and ideas were put forward. And then, for the complex part development, the process innovation and practice based on detailed parts were very active, which had important significance although there was some limitation in application. At last, for the numerical simulation technology, the mature numerical simulation technology was widely used and gradually became the necessary analysis tool for research and development. Thus, combining the above status of precision forging technology, the development trend in the future of the precision forging technology was proposed.
