Main Achievements

Theory and technology of controllable removal and increasing material machining for complex surface components

The radome should simultaneously process the comprehensive properties of high electrical performance, transparent wave, diversion, heat insulation function, high strength, and complex surface, etc. That means the radome should have both high geometric precision and excellent electrical performance, which brings much difficulty to its machining. Through many years efforts, systemic and practical theories and techniques on machining the radome have been made and a set of precision equipment are invented and been implemented into practice production. These achieved results have obtained 1 first prize of national technological invention award, which is the first time that a mechanical project is received the first prize of national technological invention award in the past 30 years. And these achieved results have also been elected as one of Ten science and technology development of China's Higher Education.

Precision machining of high performance composite components

Advanced composite materials (carbon fiber, aramid fiber) have many advantages such as high specific strength, high specific stiffness, outstanding impact resistance, excellent electromagnetic properties, etc. It has been widely used in aerospace, weapons, automobile, power and other fields. But due to its laminated structure, anisotropy, mechanical damage and poor consistency, the machining method of high quality composite components is urgently needed. So the cutting mechanism of carbon fiber composite material is investigated in theory, based on which a series of tools such as milling and drilling for carbon fiber composites are developed and put into engineering use. The actual equipment and its theory research production have passed science and technology achievements appraisal and get the full affirmation.

Investigation on mechanism for brittle material by single diamond cutting

Nanometric machining mechanism is the basic scientific problem of sub-nanometric accuracy machining and is also an international hotpot. A new single point diamond cutting method with nanometric cutting depth and m/s speed is proposed. The diamond tools with sub micro radius tool edge are developed by using ultra-precision grinding and tribochemical polishing. The related research achievements have been published in CIRP Annals-Manufacturing Technology and Nature series of Journals- Scientific Reports.

Ultra-precision grinding is the key technology to realize high efficient machining and obtain high precision, super smooth and even damage-free surface for brittle crystal substrate and optical window such as single crystal silicon and sapphire. A new chemical mechanical grinding method based on soft abrasive wheel is proposed. A series ultra-precision grinders for large size wafers of silicon, sapphire and optical window are developed for the first time in China.

Precision manufacturing of complex surface parts with macro and micro scale structure

High performance complex surface parts with cross scale structure are the key parts of the high-speed aircraft and are one type of the most difficult machining parts owing to their complex shape, the cross scale structure and anisotropic material. A new self-aligning positioning method based on binocular stereovision is proposed and a new processing technology is developed that combines cladding copper with laser/ NC micro milling. And then the equipment combined on-line visual detection and localization with laser/ micro milling is independently developed to machine different antenna for different high-speed aircraft. The actual equipment and its theory research production have passed science and technology achievements appraisal and get the full affirmation.

Fundamental theory of a new tribochemical polishing based on graphitization

It’s well known that although diamond is the hardest known material, it cannot cut transition metal such as Fe, Co, Ni due to extremely rapid tool wear. Based this phenomena, a new tribochemical polishing (TCP) method is proposed in order to meet the high-efficiency and low-damage requirements of polishing CVD diamond film and even sharpening diamond tool. Metal catalyst plays an important role in the process of TCP because of their unique characteristics including unpaired d shell electrons and vertical aligned principle. Molecular dynamics method and the first principle are introduced to investigate the mechanism of graphitization.
