Abstract: In recent years, a series of outstanding progresses and original innovations have been achieved in the fields of mechanical engineering, which provide a large number of novel theories, technologies and methodologies for our nation’s economic construction and mechanical engineering. Some of them play great significance at home and abroad. Particularly, a few advanced subjects have gained their top level position in international academic community. However it should be soberly aware that Chinese mechanical engineering science is generally in a state of backward position. The future general trends of manufacture industry are globalization, informatizaton, greening, knowledge-creating and extremalization. The overall development trend of manufacturing engineering is resource saving and environmental protection based digital network, intelligence integration, high efficient and high accuracy and extreme manufacture. Based on Delphi survey method and study, the predicted key manufacture technologies in the future will focus on the following eight fields: equipment manufacture for space and deep sea application, manufacture for information technology, micro/nano manufacture, new energy equipment manufacture, green manufacture and remanufacture, bionic manufacture, photon manufacture, and digital equipment manufacture.
