英文摘要At present, most researches focus on the machining quality of composites without special treatment, and there are only few researches on the cutting properties of composites after heat treatment. In order to obtain the parameters that have the greatest influence on the milling surface quality of SiCp/Al materials, the milling simulation experiments with control variables were carried out first. The results show that the milling speed has the greatest influence on the plastic deformation of SiCp/Al material. Then, an orthogonal experiment of three factors and four levels was carried out. The results of ANOVA show that the milling speed had the greatest effect on the roughness of the material. In order to find the optimal milling parameters, the linear regression equation was summarized, and then the Matlab Genetic Algorithm toolbox was used to find the optimal solution to the linear regression equation. The optimum milling parameters were calculated: cutting speed is 47.1 m/min, feed speed is 10 mm/min, depth of cut is 20um and optimum surface roughness is 0.036 mu m. The results of the 2D surface morphological examination show that the substrate is plastically deformed and burrs are produced. As the reinforcement phase, the particles undergo brittle fracture and are partially or completely pulled out to form pits of different sizes. The increase of milling speed will lead to the faster change of chip tumor on the tool tip, so the cutting edge is not stable, and the cutting force fluctuations will become larger, and the surface quality will decrease. By observing the surface and subsurface morphology characteristics of the material, the causes of surface defects can be obtained: the particles on the side of the milling groove are squeezed to produce brittle fracture and form pits on the surface. The subsurface is not only easy to produce pits, but also the particles are squeezed by the milling force, resulting in cavity defects.
