摘　　要：为实现SiC_(p)/Al复合材料的高精高效加工,采用复合旋转超声与磨削、电加工等特种加工方法,研究了旋转超声机械-电解复合加工机理,分析了多能场加工参数的作用效果,探讨了加工效率、表面质量等指标,建立了数学分析模型,设计构建旋转超声复合多能场加工系统。采用直径4 mm电极和4 V电解电压,对碳化硅质量分数为30%的SiC_(p)/Al复合材料进行旋转超声及一维、二维超声多能场加工对比试验。结果表明:超声多能场加工能显著降低表面粗糙度,可加工出较光滑的平面和微结构;二维旋转超声复合加工相较于一维加工的效率提高20%以上,加工精度可达0.01 mm,表面粗糙度达Ra1.6μm。超声多能场加工过程稳定,具有显著的技术复合优势。Effectively combining traditional grinding processing with special processing methods such as rotary ultrasonic and electrical machining to achieve effective processing of SiC_(p)/Al composite materials.Study the mechanism of rotary ultrasonic mechanical electrolytic composite machining,analyze the effect of multi energy field parameters,explore machining efficiency and surface quality,and establish mathematical models.Design and develop a rotating ultrasonic composite multi energy field machining system.Using a@4 mm electrode and 4 V electrolytic voltage,the SiC_(p)/Al composites with 30%silicon carbide content were subjected to rotational ultrasonic and one-dimensional and twodimensional ultrasonic multi-field machining tests.The results showed that the ultrasonic multi-energy machining could significantly reduce the surface roughness of a single rotary ultrasonic machining,and process a smoother plane and micro-structure.At the same time,compared with one-dimensional machining,the efficiency of two-dimensional rotary ultrasonic composite machining can be increased by more than 20%,the machining accuracy can reach 0.01 mm,and the surface roughness is Ral.6μm.The ultrasonic multi-energy field processing process is stable and has significant multi-technology compound advantages.
