碳纤维增强陶瓷基复合材料(Cf/SiC复合材料)具有良好的化学和热稳定性、高比强度、耐高温以及低密度等优点,被广泛应用于航空航天、高速列车以及核能等领域.目前陶瓷基复合材料构件普遍采用近净成形技术制备,但仍需进行二次加工以满足最终装配的尺寸精度和几何公差.然而,由于Cf/SiC复合材料具有各向异性和多相非均质的材料特性,其高效低损伤加工需求备受关注.因此,系统地综述了文献报道的Cf/SiC复合材料超声振动辅助铣削加工技术相关研究进展.首先概述了陶瓷基复合材料传统机械加工以及特种能场辅助加工技术的研究现状.其次,从陶瓷基复合材料超声振动辅助铣削加工过程中直角切削试验和有限元仿真两方面总结了材料去除机理和超声作用机制;介绍了陶瓷基复合材料超声振动辅助铣削中切削力建模的方法和陶瓷基复合材料加工表面损伤及其剩余强度方面的研究.最后,分析了陶瓷基复合材料超声振动辅助铣削加工的发展趋势以及展望未来研究方向.
Carbon fiber reinforced ceramic matrix composites(Cf/SiC composites)have the advantages of good chemical and thermal stability,high specific strength,high temperature resistance and low density.They are widely used in aerospace,high-speed trains and nuclear energy.Currently,ceramic matrix composites(CMCs)components are generally prepared by near net forming technology.However,secondary machining is still required to meet the dimensional accuracy and geometric tolerance of the final assembly.Owing to the characteristics of Cf/SiC composites such as anisotropy and multiphase heterogeneity,the need for efficient and low-damage machining of Cf/SiC composites is concerned.Hence,the research progress of ultrasonic vibration-assisted milling(UVAM)technology for Cf/SiC composites reported in the literature are systematically reviewed.Firstly,the research status of traditional machining and special energy field assisted machining technology of CMCs are summarized.Secondly,the material removal mechanism and ultrasound action mechanism are summarized using the orthogonal cutting tests and finite element simulation during UVAM of CMCs.Then,the modeling method of cutting force of CMCs in UVAM is discussed,and the research on machined surface damage and residual strength of CMCs is introduced.Finally,the development trend of UVAM of CMCs and the outlook on future research directions are analyzed.
