The influence analysis of machining mechanism is that new technologies and new equipment keep emerging in recent years, and the research on precision machining should be strengthened constantly to explore new processing methods. In terms of traditional processing, ultra-precision machining, precision high-speed machining, precision grinding belt grinding and abrasive machining of diamond tools have achieved good results; From the perspective of non-traditional processing, laser beam, electron beam, ion beam and other high energy beam precision processing, ultrasonic processing, electric discharge processing and electrochemical processing have obvious advantages, especially the application of combined processing, such as ultrasonic honing, electrolytic grinding and other technologies, the significance of the breakthrough development is mainly manifested in the clear proposed removal processing, The effective integration of machining and deformation machining, especially the advantage of superposition machining rapid prototyping, plays an important role in promoting the development of machining technology.
