Abstract
With regard to the lack of clearance about the influence of ultrasonic vibration frequency and amplitude on the grinding force,surface roughness and microstructure of SiCf/SiC composites during grinding,this paper conducts the ultrasonic vibration assisted grinding experiments on SiCf/SiC composites under different vibration frequencies and amplitudes.The results show that the introduction of ultrasonic vibration and the increase of vibration frequency both can effectively reduce the grinding force and surface roughness,but the change of amplitude has little effect on the grinding force and surface roughness.The introduction of ultrasonic vibration promotes fiber breakage,and the length of the fiber in the wear debris decreases,which helps to improve the surface processing quality.关键词
