This paper first discusses development of the new-generation intelligent manufacturing from the aspects of problems and challenges of the manufacturing industry, major opportunities brought by new-generation artificial intelligence, and core technologies of the new round of industrial revolution. By analyzing the evolution process of intelligent manufacturing, this paper points out that the process of development from traditional manufacturing to intelligent manufacturing is also a process of development from the original human-physical systems (HPS) to a human-cyber-physical systems (HCPS). HCPS reveals the basic principles of intelligent manufacturing development and is the theoretical basis for supporting the development of the new-generation intelligent manufacturing. Based on system integration of HCPS and intelligent manufacturing, the prospect of the new-generation intelligent manufacturing is described from the perspective of the revolutionary changes brought to the manufacturing sector and to human society.
