| 摘 要： | 用聚晶金刚石PCD刀具对SiC晶须增强铝复合材料SiCw／2024进行了精密超精密切削试验，并用原子力显微镜和电子探针扫描显微镜进行了检测分析，结果证明，SiCw／2024铝复合材料加工表面粗糙度值达到超精密级的最大障碍在于SiC晶须拔出或压入型的破坏方式，而直接剪断的破坏方式则几乎无影响；SiCw／2024超精密加工表面会产生很薄的加工变质层。 |
| 关 键 词： | SiC晶须 铝复合材料 超精密加工 加工变质层 表面粗糙度 表面微观分析 |

| Abstract: | In the paper,experiments on precision and ultraprecision machining of the SiC whisker reinforced aluminum composites,SiC w/2024,are carried out by Polycrystalline Diamond (PCD) cutter. In addition, Atomic Force Microscope(AFM) and Electronic Probe and Scanning Microscope(EPSM) are used to measure and analyze.And following conclusions are drawn: the greatest difficulty that the surface roughness value of aluminum composite SiC w/2024 approaches to that of ultraprecision level depends on the destroying means of the pulling and pushing type of SiC whisker and is not almost affected by the destroying means of the direct cutoff; there is also a very thin cutting damaged layer on the surface of PCD tools in precision and ultraprecision machining process. |
| Keywords: | SiC whisker aluminum composite ultraprecision machining surface roughness cutting damaged layer |
