AbstractIn order to improve the surface grinding quality of 60% volume fraction aluminum matrix composites, the cutting tool models with different rake angles are established, the grinding process is simulated, and the material removal mechanism and the broken state of SiC particles are obtained. Through single factor experiment, the 60% volume fraction SiCp/Al2024 composites are ground by diamond grinding rod with 3 mm diameter, the influence of the grinding depth (a(p)) on the surface roughness (Ra) value is discussed, and it is concluded that as the a(p) increases, the Ra also increases, and the a(p) increases from 10 mu m to 30 mu m, the Ra rises from 0.332 mu m to 0.71 mu m when spindle speed (n) is 14,000 rpm and feed rate (v(w)) is 0.003 m/min. Then the surface and sub-surface quality of SiCp/Al2024 composites with meso-scale grinding is investigated. Meanwhile, the influence mechanism of a(p) on surface quality is put forward, and the influence of different a(p) on the fragmentation of SiC particles in sub-surface layer is discussed, which verifies the correctness of grinding simulation. The relevant research and theoretical model are of great significance to the study of grinding properties of composite materials.
