Abstract: Different from traditional machining processes, the manufacturing technology of Functional Surface Structure, aims to produce structures of various morphologies, scales, dimensions and functions on machined surfaces. Functional surface structure relates to many disciplines and shows its advantages in many technical applications. It can play a crucial role in promoting energy efficiency and emissions reductions in conventional energyintensive industries, enhancing the performance of the equipments in advanced opto-electronics industry, defense industry, automotive industry and agricultural engineering, and stimulating the development of new industries, e.g. new energy. The research of the functional surface structure is extending from special manufacturing processes to multi-disciplines integrated design, scientific problems and key technologies in manufacturing engineering. Various functional surface structures are classified according to their scales, dimensions and functions, and their specific characters are discussed in detail. The latest research and applications, the challenges and future trends of functional surface structures are also presented and analyzed.

Key words: Composite / coupling functional structure, Functional surface structure, Micro functional structure
