| 摘 要： | 采用普通磨削和超声辅助磨削工艺对C/Si C复合材料进行加工,对不同加工工艺参数获得的C/Si C复合材料进行表面状态表征及力学性能的测试。结果显示在磨削深度0.05 mm,进给速度600 mm/h,转速1 600 r/min,超声频率14 k Hz的工艺参数匹配条件下,所得到的C/Si C复合材料的表面粗糙度最小,弯曲强度最大。表明超声辅助磨削加工工艺对材料力学性能损伤较小。

| Abstract: | In this paper, C/ SiC composites were machined by traditional grinding and ultrasonic vibration-assisted
grinding. Surface characterizations and mechanical properties of the C/ SiC composites grinded under different processing
parameters are measured. Results of performance test indicated that the composite material machined by ultrasonic
assisted grinding process obtained the better surface roughness quality and the greater bending strength,the best
processing parameters were: grinding depth 0. 05 mm, feed velocity 600 mm/ h, speed 1 600 r/ min, ultrasonic frequency
14 kHz. It shows that ultrasonic vibration-assisted grinding has the lower damage to material mechanical properties. |
