Aluminum matrix composite fsic / (A1) with high specific strength, high ratio stiffness, high thermal stability, high dimensional stability and other outstanding features , weapons, aerospace, automobile manufacturing and electronics industry a wide range of applications prospects . Currently the composite sic/A1 processing methods is the use of PCD tool for cutting , but due to the presence of SiC particles , the material has the characteristics of the \processing cost is high . Therefore severely limited the wide application of this material . It is therefore imperative to Higher the sic/A1 composites processing methods . The main subject of the use of the milling processing sic/A1 composite machining , milling force and surface roughness were investigated through the study of the process parameters optimization of process parameters . First, according to the grinding principles and mechanics of composite materials knowledge , combined with milling machining characteristics , milling processing material removal process analysis , combined with the correctness of the experimental verification of theoretical analysis . Secondly , the study of the wheel speed the milling processing sic/A1 composite material , feed rate, and the milling depth of the impact of process parameters on the milling force law , drawn in orthogonal experimental data were analyzed after the experience of the milling force formula. Combined with theoretical analysis. Finally, the surface roughness of the various process parameters affecting the processing processing experiments , the use of single-factor experimental study of process parameters on surface roughness , using orthogonal experimental the milling processing sic/A1 composite process parameters and surface roughness of the empirical formula , for a larger material removal efficiency and better surface roughness of the combination of parameters obtained by a combination of milling processing , surface roughness after 1 258um .
