Abstract
This paper deals with the grinding performance of SiC-based ceramic matrix composites (CMCs) with a mounted wheel. A vitrified bonded superabrasive stone was applied to grind the CMCs. To investigate the influence of grinding conditions on the machinability, the specific grinding energy and tool wear were measured experimentally. The influence of fiber orientation on the surface quality was also evaluated. In addition, the grinding performance of CMCs was compared with that of atmospheric sintered silicon carbide. The results showed that the CMCs were ground with a depth of cut of 900 μm without any wear on the mounted wheel. The machinability of CMCs was superior to that of atmospheric sintered silicon carbide. In addition, the surface roughness on CMCs was influenced by the fiber orientation.
