With the volume fraction of SiC increasing, the machinability and electrical machining performance of SiCp/Al metal matrix composites (SiCp/Al MMCs) decreases gradually. Therefore, it is difficult to machine small holes in high volume fraction SiCp/Al MMCs. Based on the material properties and grinding mechanism, the small hole …
