| Abstract | SiCp/Al composites contain fine reinforcing particles with high hardness and rigidity, which makes the processing more difficult. The surface roughness prediction model was established and the micro-grinding mechanism was revealed. A non-homogeneous finite element simulation model for the high-volume fraction SiCp/Al composites grinding process was established. Based on the response surface method (RSM), an electroplated diamond grinding rod with a diameter of 1 mm was used to conduct micro-grinding experiments on SiCp/Al composite materials whose SiC particles accounted for 60%. The results show that the spindle speed has the most significant influence on the surface roughness, followed by grinding depth and feed rate. The minimum surface roughness of micro-grinding is 0.51 mu m. Based on the analysis of micro-grinding simulation model and the surface morphology detected by scanning electron microscopy, the grinding mechanism of high-volume fraction SiCp/Al composites were put forward which mainly embodied in brittle fracture and pull-out of particles. |
