High-volume SiCp/Al materials were processed by Laser-induced Oxidation assisted machining technology.We obtained the laser induced oxidation process and oxidation mechanism, through the analysis of the average laser power, scanning speed, scanning distance and other factors on the oxidation effect.The results show that:1) In an oxygen-rich environment, the oxide layer will eventually exist as mullite(2 Al2O3·SiO2)after sufficient reaction of the surface material. 2) When the average laser power is 6W, the laser scanning speed is 1 mm/s, and the laser scanning distance is 10 μm, the optimal combination of parameters is obtained. The results show that the thermal hardening layer and dense layer are the least and the hardness is low, which is suitable for high efficiency and precision milling; 3)The laser induced oxidation assisted milling technology can significantly improve the processing efficiency, the material removal rate is greater than 3000 mm3 /min, the surface roughness value after Precision machining is better than Ra0.4 μm.
