微纳织构椭圆振动辅助切削加工关键基础理论研究

Manfacturing requirements with low cost, high efficiency and flexible large batches and widely application vision of hierarchical micro-nano textures, the project explores the key basic theory of locus planning and controlling of ultrasonic elliptical vibration assisted cutting driven by hierarchical micro-nano textures in order to solve the generation of micro-nano textures on complicated surface. Based on the analysis of cutting path planning for micro-nano textures, the generation and compensation method of elliptical vibration cutting locus are investigated by using the tensor theory,mapping mechanism and moving frame. The modeling method of micro-nano texturing topography and simulation is studied by using the sweeping and mapping method. Based on data filter theory, multi-error compensation and precise control methods are explored by using the combination of off-line calibration and on-line adjustation of structure performance for the designed ultrasonic elliptical vibration cutting equipment.The adaptive control model of elliptical vibration locus is established. The synchronic control method of ultrasonic elliptical vibration cutting locus is proposed based on the above research . The experimental system of ultrasonic elliptical vibration assisted cutting hierarchical micro-nano textures is established, which is verified by the cutting process of typical hierarchical micro-nano textures for drag reduction The precise manufacturing of micro-nano textures is realized by combining the error compensation,performance compensation of vibration mechanism and control compensation of elliptical vibraition cutting locus and the above research provides the theory support for high efficient, controlled manufacturing of hierarchical micro-nano textures.
