Effect of grinding wheel type and cooling method on grinding quality of SiCf/SiC ceramic matrix composites
Published 2025-04-01“…Three different regions of each sample were selected for measurement, and average values were taken to reduce the measurement error. Additionally, to analyze the wear mechanism of the grinding wheels, the wear morphology of the grinding wheel surface after grinding was observed using a VHX2000c ultra-depth-of-field three-dimensional microscope, and the failure modes of different grinding wheels under different grinding conditions were compared and analyzed.ResultsGrinding wheel type and cooling method have a significant effect on the grinding performance of SiCf/SiC composites. …”
